What should you focus on for an IT support interview?
What makes these interviews different?
Compared with the wider interview sample, these interviews covered more end-user support, customer support, troubleshooting, networking, and Windows Server and Active Directory. Your checks should cover both finding the problem and helping the user.
Most questions were labelled mid-level: 56% were mid-level and 33% junior. Can you explain how you would investigate an issue, choose your next step, and explain it to someone without a technical background?
Can you explain which ticket you would handle first?
Ticket management came up in 40 of 99 interviews. The most repeated question, asked in 7 of 99 interviews, covered priorities based on urgency, impact, and resolution targets.
Try the scenario from these interviews: a clinician is locked out, while another customer reports missing session data. Can you explain what you need to know before choosing which case to handle first?
- What would you ask to understand the impact and urgency?
- How would you account for the service-level agreement, or SLA?
- What would you document before an escalation or handoff?
Can you investigate without guessing or blaming the user?
Questions covered frustrated users, unfamiliar features, and ways to tell a product bug from a permissions or workflow issue. Check whether you can walk through an application problem from the first report to a verified fix.
- What information would you gather before troubleshooting?
- How would you reproduce the issue and find its cause?
- If employees see different information in the same feature, what would you investigate?
- How would you research an unfamiliar feature without giving unverified advice?
- How would you check that your fix worked?
Can you explain technical checks and protect the user?
Desktop and networking questions covered account access, printers, operating systems, DNS, DHCP, Wi-Fi, and VPNs. Can you name the Windows command that shows full IP configuration, including the subnet mask? Can you explain which details you would check?
Security questions also covered identity checks and healthcare privacy. Can you describe how you would verify someone’s identity before helping with account access? Can you explain how you would protect patient information while providing support?
Do you need to write code?
Code-writing tasks appeared in 4 of 99 interviews. Check whether you can query the most recent payment records and rank users by spending. Can you handle nulls, users with no orders, and ties?
The questions also covered APIs, webhooks, and support automation. Can you explain how you would investigate an API or webhook problem and handle errors in a support workflow?

How do you prioritize competing support tickets by urgency, impact, and resolution targets?
Asked in 7 of 99 interviews · last asked Oct 8 · Scenario · Mid-level
Show answer
I prioritize tickets by business impact, urgency, and agreed response and resolution targets. I check who is affected, what work is blocked, and whether there is a workaround. If priorities are equal, I handle the ticket closest to its deadline first. I reassess as conditions change, keep users updated, and escalate when targets are at risk.
- Impact means how many people are affected and how critical the affected work is.
- Urgency depends on how soon serious harm or disruption could occur; a workaround may reduce it.
- Use agreed priority rules and service-level agreement (SLA) targets, not who complains loudest.
- Reassess priorities and ask for help when competing tickets put deadlines at risk.
What the interviewer checks: The interviewer checks whether you can balance business needs and deadlines while keeping users informed.
Other ways it was asked
- “How do you prioritize multiple support requests?”
- “How do you prioritize support tickets when many requests arrive at once?”
- “When you have multiple support requests that all look equally urgent, how do you prioritize which one to handle first, and what factors guide that choice?”
Two urgent cases arrive together: one clinician is locked out, and another customer reports that session data appears to be missing. How would you prioritize them?
Asked in 5 of 99 interviews · last asked Aug 19 · Scenario · Mid-level
Show answer
I would quickly assess both cases and prioritize immediate risks to patient care or ongoing data loss. I would check whether the lockout blocks care and whether the missing data affects others. I would seek parallel help and escalate suspected data loss. I would tell both customers who owns their case, the next step, and when to expect updates.
- Prioritize by impact, urgency, and safe workarounds, not ticket order.
- Verify the clinician’s identity before restoring access; do not bypass security.
- Check whether data is truly missing or simply not visible; avoid changes that could worsen loss.
- Assign help where possible, explain priorities, and give update times without promising a fix time.
What the interviewer checks: The interviewer is checking whether you assess risk, protect patient care and data, and communicate clearly under pressure.
Other ways it was asked
- “Imagine two urgent tickets arrive at once: a clinician is locked out, and another user reports missing data. How do you decide what to tackle first, and what do you communicate?”
- “Two urgent cases arrive at the same time: one clinician is locked out while another customer reports that session data may be missing. How would you prioritize them, and what would you communicate to each customer?”
- “Two urgent cases arrive at once: one clinician is locked out, and another customer reports missing session data. How would you assess the risks?”
How would you distinguish a product bug, permissions problem, or workflow issue without blaming the customer?
Asked in 4 of 99 interviews · last asked Aug 25 · Scenario · Mid-level
Show answer
I would ask what the customer wants to do, then walk through the steps together and note any errors. I would compare the steps with the supported workflow, check their access, and try to reproduce the issue. I would explain what I found without blame, then guide them, request approved access, or report a suspected bug.
- Ask about the expected result, actual result, and exact steps.
- Check required permissions without granting unnecessary access.
- Test the supported workflow with an authorized account; compare results and errors.
- Describe what the system requires, not what the customer did wrong.
What the interviewer checks: The interviewer is checking whether you can isolate the cause while keeping the customer respected and involved.
Other ways it was asked
- “How would you determine whether a customer is facing a product defect, a permissions problem, or simply needs help with the workflow?”
- “How would you determine whether a customer is facing a product defect, a permissions problem, or simply needs help using the correct workflow?”
- “Suppose a customer says a feature is not working, but you suspect it may be a workflow or training issue rather than a product defect. How would you determine the difference without making the customer feel blamed?”
How would you research an unfamiliar feature and help a customer without giving unverified advice?
Asked in 4 of 99 interviews · last asked Aug 25 · Scenario · Mid-level
Show answer
I would explain that I need to verify the feature before recommending a fix. I would confirm the customer's goal and product version, and check official documentation and known issues. Before suggesting a workaround, I would verify its safety and test it in a safe environment if possible. If still unsure, I would escalate and agree on an update time.
- Confirm the customer's goal, product version, permissions, and any error messages.
- Use current official documentation and approved support notes, not unverified forum advice.
- Check whether a workaround risks data loss, security problems, or service disruption.
- If verification is not possible, explain the limit, escalate, and keep the customer updated.
What the interviewer checks: The interviewer is checking whether you research carefully, avoid guessing, and manage the customer's expectations.
Other ways it was asked
- “A customer asks about a product feature you have never supported and wants an immediate workaround. How would you respond, and what would you verify before recommending anything?”
- “A customer asks about a product feature you have never supported and wants an immediate workaround. How would you respond?”
- “A customer calls about a feature you have never supported before and expects an immediate answer. How would you handle the situation?”
How do you protect patient information and stay HIPAA compliant while providing technical support?
Asked in 4 of 99 interviews · last asked Oct 16 · Scenario · Mid-level
Show answer
I verify the user's identity and access only the patient information needed to fix the issue. I use approved support tools and secure channels, and keep patient details out of tickets unless required by policy. I follow access controls, never share passwords, and report suspected exposure immediately through the required process.
- Verify identity and permission before resetting passwords or changing access.
- Limit access to what the task requires; avoid unnecessary copies of patient data.
- Use approved remote support tools and protect logs, screenshots, and attachments.
- Follow security policies, complete required training, and report suspected incidents promptly.
What the interviewer checks: The interviewer checks whether you protect patient data, respect access limits, and follow approved support and incident procedures.

- “How do you protect sensitive healthcare information while troubleshooting a customer's access or application issue?”
- “How do you protect sensitive healthcare information while troubleshooting access or application problems?”
- “What are the basic rules for keeping systems secure in a HIPAA-regulated healthcare environment?”
Walk me through a complex technical problem you solved, your troubleshooting approach, and the outcome.
Asked in 3 of 99 interviews · last asked Oct 15 · Behavioral · Mid-level
Show answer
I fixed a VPN issue where users could connect but could not open internal sites. I checked who was affected, reproduced the issue, and compared DNS settings and lookup results on working and failing devices. The VPN was assigning the wrong DNS server, so I corrected its settings through change control. Users then confirmed access worked.
- Explain the symptoms, user impact, and your own role.
- Use test results to narrow down causes, rather than changing settings at random.
- Get approval for risky changes and prepare a rollback plan.
- Confirm the fix with users and document the cause and solution.
What the interviewer checks: The interviewer is checking whether you investigate problems logically, make safe changes, and confirm the outcome.
Other ways it was asked

A user reports that an application is not working. How would you investigate and resolve the issue?
Asked in 3 of 99 interviews · last asked Sep 27 · Scenario · Junior
Show answer
I would ask what happens, the exact error, when it started, and whether others are affected. I would check recent changes, try to reproduce the issue, and review relevant logs, access, and connections. I would test a safe fix, confirm it works with the user, and document the result or escalate with my findings.
- Clarify the symptoms and impact before choosing a fix.
- Check whether the issue affects one user, one device, or several users.
- Protect unsaved work and test one change at a time.
- Keep the user informed and escalate when needed with errors and troubleshooting steps.
What the interviewer checks: The interviewer is checking whether you troubleshoot logically, communicate clearly, and confirm the issue is resolved.
Other ways it was asked
- “What would you do if a user reported that an application was not working?”
- “A user says the application is not working. What would you do?”
Which Windows command shows full IP configuration, including the subnet mask, and what details would you check?
Asked in 3 of 99 interviews · last asked Oct 5 · Tooling · Junior
Show answer
I use `ipconfig /all` to show the full IP configuration on Windows. I check the active adapter’s IP address, subnet mask, default gateway, DNS servers, and DHCP status. An unexpected 169.254.x.x IPv4 address can mean the computer could not get an address from DHCP.
- Check the active adapter, not a disconnected Wi-Fi or Ethernet adapter.
- Compare the IP address, subnet mask, gateway, and DNS servers with the expected network settings.
- Check whether DHCP is enabled and review the DHCP server and lease details.
- Plain `ipconfig` also shows the IPv4 subnet mask; `/all` adds more details.
What the interviewer checks: The interviewer is checking whether you know the command and can spot basic network configuration problems.
Other ways it was asked
- “What command would you use on a Windows 10 computer to display the subnet mask?”
- “What do you check with ipconfig /all?”
- “Which command would you use to view a computer’s full IP configuration?”
A customer reports that information appears differently for two employees using the same feature. How would you investigate the difference?
Asked in 2 of 99 interviews · last asked Aug 20 · Scenario · Mid-level
Show answer
I would compare what each employee sees and confirm they are using the same steps and records. I would check their permissions, filters, settings, and app versions. Then I would test one difference at a time and check logs for clues. I would confirm whether the difference is expected or a fault before making changes.
- Get the exact steps, expected results, screenshots, and any error messages.
- Compare access rights, selected records, filters, and user settings.
- Test whether the issue follows the account or the device, without sharing passwords.
- Change one thing at a time, and do not grant extra access just to match results.
What the interviewer checks: The interviewer is checking whether you compare conditions systematically while protecting access and data.
Other ways it was asked
- “A customer says a feature works for one employee but not another. How would you investigate the issue?”
What questions would you ask and information would you gather before troubleshooting a reported issue?
Asked in 2 of 99 interviews · last asked Oct 22 · Scenario · Mid-level
Show answer
I would ask what is failing, what should happen, when it started, and who is affected. I would ask for exact error messages, recent changes, and any steps already tried. I would also gather device, operating system, and application details, check the business impact, and ask whether the issue happens every time.
- Confirm the symptoms, expected result, and exact error message.
- Find out who is affected and which work is blocked.
- Ask when it started, how often it happens, and what changed recently.
- Record relevant system details and previous troubleshooting steps to avoid repeating work.
What the interviewer checks: The interviewer is checking whether you gather clear facts, judge urgency, and avoid guesses or repeated work.
Other ways it was asked

- “When troubleshooting a complex technical issue, what information would you gather at the outset to avoid unnecessary delays?”
What's one assumption you try not to make when starting a new case?
Asked in 2 of 99 interviews · last asked Aug 20 · Scenario · Mid-level
Show answer
I try not to assume that a familiar symptom has the same cause as a previous case. I ask what happened, who is affected, and whether anything changed. Then I use simple checks to test the likely cause before making changes.
- Treat past cases as clues, not proof.
- Confirm the symptoms and who is affected.
- Test the likely cause before applying a fix.
What the interviewer checks: The interviewer is checking whether you gather facts instead of jumping to conclusions.
Other ways it was asked
- “What’s one assumption you try not to make when starting a new case?”
How do you keep a customer informed during an unresolved investigation without overpromising?
Asked in 2 of 99 interviews · last asked Aug 25 · Scenario · Mid-level
Show answer
I explain what I know, what is still unclear, and what I will check next. I acknowledge the impact and agree on a time for the next update, even if there is no progress. I commit to that update, not a fix date I cannot confirm.
- Use plain language and separate confirmed facts from possible causes.
- Set a clear update time and follow through, even without new findings.
- Offer a safe workaround if available, and explain its limits.
- Explain any escalation and remain the customer's contact.
What the interviewer checks: The interviewer is checking whether you communicate clearly, take responsibility, and set honest expectations while the issue remains unresolved.
Other ways it was asked
- “If the root cause isn’t obvious and you’re still mid-investigation, how do you keep the user aligned without overpromising?”
- “You have been working on a customer's technical issue for several hours without finding a fix. How would you keep the customer informed during the ongoing case?”
How would you handle a client call when you do not know the answer and nobody can help?
Asked in 2 of 99 interviews · last asked Sep 28 · Scenario · Mid-level
Show answer
I would stay calm, admit I need to check, and avoid guessing. I would ask clear questions, record the details, and check trusted guides or known fixes. If I could not solve it during the call, I would agree on a time to update the client and keep ownership until it is resolved.
- Be honest about what you do not know, without blaming others.
- Ask about the problem, its impact, and any error messages.
- Use trusted sources and avoid changes that could make things worse.
- Promise an update time, not a fix time you cannot guarantee.

- “If you are the only technical representative on a client call and are asked a question you cannot answer, what do you do?”
- “Imagine you're the only person available to the caller and you don't immediately know the answer. How would you keep the caller confident in you and the business while you figure it out?”
Imagine a customer asks, “Can you promise we're 100% secure after this patch?” How would you respond?
Asked in 2 of 99 interviews · last asked Oct 16 · Scenario · Mid-level
Show answer
No, I cannot promise 100% security after this patch. It fixes specific security issues, but other risks may remain. I would confirm that it installed correctly and explain the next steps, such as keeping other software updated and monitoring for threats.
- Do not guarantee complete security.
- A patch fixes specific issues, not every possible weakness.
- Check that the patch installed successfully.
- Explain remaining risks and next steps in plain language.
What the interviewer checks: The interviewer is checking whether you explain risk honestly and reassure the customer without making false promises.
Other ways it was asked
- “If a customer asks, “Is my system fully secure after patching?”, what would you say?”
How would you research a customer's Gmail issue and structure a clear written support response?
Asked in 2 of 99 interviews · last asked Aug 25 · Scenario · Junior
Show answer
I would ask what happens, when it started, and whether Gmail is affected in the browser, app, or both. I would check Google's status dashboard and Gmail Help, then test safe steps that match the symptoms. My written reply would state the issue, give numbered steps, explain the expected result, and say what to send back if it still fails.
- Ask for the exact error, device, and recent changes; never request passwords or verification codes.
- Use official Google guidance and check for outages before suggesting changes.
- Give short, numbered steps, starting with safe checks that do not risk data.
- Explain what should happen and when to follow up or escalate.
What the interviewer checks: The interviewer is checking whether you research reliably, troubleshoot safely, and write instructions the customer can follow.
Other ways it was asked
- “How would you research an unfamiliar Gmail support issue before responding to the user?”
How do you track competing tickets and follow-ups so no issue falls through the cracks?
Asked in 2 of 99 interviews · last asked Aug 20 · Behavioral · Mid-level
Show answer
I track every issue in the ticket system, with an owner, clear notes, and a next action. I set priorities by impact, urgency, and response targets, and use reminders for follow-ups. I review open and overdue tickets daily, including those waiting on someone else. If work is delayed, I update the user and escalate when needed.
- Give each ticket an owner and a dated next action.
- Prioritize by impact, urgency, and service targets, not just arrival order.
- Review waiting and overdue tickets; use reminders rather than memory.
- Keep users informed and confirm the fix before closing.
What the interviewer checks: The interviewer wants to see a reliable tracking routine, clear priorities, and ownership through resolution.
Other ways it was asked
- “How do you ensure that all issues are eventually addressed without any falling through the cracks, even if some are delayed?”
- “Describe how you manage competing tickets without missing follow-ups.”
What would you document in a support ticket to support handoffs, audits, and future troubleshooting?
Asked in 2 of 99 interviews · last asked Aug 24 · Tooling · Mid-level
Show answer
I document the issue, affected users and systems, impact, and exact error messages. I keep a dated timeline of checks, results, changes, and approvals so nobody repeats the same work. For handoffs, I name the owner and next steps. At closure, I record the fix and how recovery was confirmed, without including passwords or unnecessary personal data.
- Record impact, scope, priority, and relevant evidence.
- Use timestamped work notes for actions, results, changes, and approvals.
- State the current status, next owner, pending tasks, and next update time.
- Separate resolution notes from work notes; include verified fixes and reusable steps.
What the interviewer checks: The interviewer checks whether your notes let others continue work, trace decisions, and reuse a verified fix.
Other ways it was asked
- “How do you decide what to document so the next person doesn’t have to redo your work?”
- “In an ITSM tool, how do you structure incident timeline, work notes, and resolution notes so they are clear for audit handoff and later knowledge article reuse?”
How do you use ticketing tools and ITIL processes to manage support requests, incidents, problems, and escalations?
Asked in 2 of 99 interviews · last asked Sep 21 · Tooling · Mid-level
Show answer
I use the ticketing tool to record, categorize, prioritize, and track each ticket against its SLA. I follow ITIL processes to restore service for incidents, fulfill service requests, and link recurring incidents to problem records. I escalate when specialist help is needed or deadlines are at risk. I document actions, keep users informed, and confirm resolution before closing.
- Set priority by business impact and urgency, not just arrival order.
- Follow approval steps for service requests, such as access or equipment.
- Incident management restores service; problem management investigates causes and prevents repeat incidents.
- Escalate to specialists or management as needed, with clear notes and ownership.
What the interviewer checks: The interviewer checks whether you organize support work, apply ITIL correctly, and keep tickets moving with clear communication.
Other ways it was asked
- “How do you use ticketing systems and ITIL processes to manage incidents, service requests, problems, and escalations?”
- “How do you use incident or ticketing tools such as Jira or ServiceNow to manage and prioritize support tickets?”
My internal speakers are not working. What steps would you take to troubleshoot the issue?
Asked in 2 of 99 interviews · last asked Oct 2 · Scenario · Junior
Show answer
I would check the volume, mute settings, and selected sound output, then disconnect headphones and Bluetooth audio devices. I would test another app and use headphones to help narrow down the cause. Next, I would restart the computer and check the audio driver. If the speakers still failed, I would run hardware diagnostics and arrange repair if needed.
- Check both system and app volume, and select the built-in speakers as the output.
- Try another app or audio file to see whether the problem affects all sound.
- Check for a disabled audio device; update or roll back the driver if appropriate.
- Headphone sound helps narrow the cause but does not prove the speakers are faulty.
What the interviewer checks: The interviewer is checking whether you start with simple checks and separate settings, software, and hardware problems.
Other ways it was asked
- “If my computer's internal speakers were not working, what steps would you take to troubleshoot the issue?”
When a VPN user can connect but can’t reach any internal subnets, how do you distinguish routing issues from DNS issues and split-tunnel policy problems?
Asked in 2 of 99 interviews · last asked Sep 3 · Scenario · Mid-level
Show answer
I test an internal service by IP, then by name. If only the name fails, I check VPN DNS settings and resolution. If IP fails, I check routes, subnet overlap, and firewall rules. I compare routes with policy: split tunnel carries selected networks; full tunnel normally carries all traffic.
- Test a known service port; failed ping alone does not prove a routing problem.
- Check that internal destinations use the VPN route, not an overlapping local network.
- Confirm internal names resolve correctly using the intended DNS servers, and those servers are reachable.
- Check split-tunnel subnet lists or full-tunnel default routes; if correct, investigate firewall rules and return routes.
What the interviewer checks: The interviewer checks whether you can separate name resolution failures from routing and VPN policy problems.
Other ways it was asked
- “A user connects successfully, gets an assigned VPN IP, but cannot reach any internal subnets. What would you check first regarding routes, DNS, and split tunnel versus full tunnel policy?”

How this list is made
Every question here was asked by a real interviewer in a real job interview that a candidate ran MeetAssist in. After the call, the interviewer's questions are pulled from the transcript. Practice sessions, tests, exams and anything that was not a job interview are dropped.
Questions are rewritten so they make sense on their own: names of people, employers and clients are removed, and speech-to-text mistakes are fixed. Small talk, logistics and questions about one candidate's own résumé are left out. Rephrasings of the same question are merged, and the count is the number of different interviews it came up in.
The interviews come from candidates who use MeetAssist, so they lean towards software, data and AI roles: the shares describe these interviews, not every IT Support and Help Desk interview. Answers to the most asked questions are written and checked by an editor; a "common mistake" is shown only when reviews of real answers in these interviews show it, with the count.
99 interviews, 51 candidates, Jan 2026 to Oct 2026. Updated every month with new interviews.
