What is cloud computing, and what are its fundamental concepts?
Asked in 6 of 942 interviews · last asked Oct 22 · Concept · Junior
Show answer
Cloud computing means using computing resources, such as servers, storage, and software, on demand over a network. Users can get resources themselves from a shared pool and quickly increase or reduce capacity. Usage is measured, and public cloud services commonly charge based on what you use.
- Core concepts are self-service, network access, shared resources, rapid scaling, and measured usage.
- Service models include IaaS for infrastructure, PaaS for application platforms, and SaaS for ready-to-use software.
- Deployment models include public, private, and hybrid clouds.
- Security responsibilities are shared between provider and customer; the split depends on the service model.
What the interviewer checks: The interviewer checks whether you understand cloud computing beyond simply renting remote servers.

What is multitenancy?
Asked in 4 of 942 interviews · last asked Jul 16 · Concept · Junior
Show answer
Multitenancy means one software system serves multiple customers, called tenants, while keeping their data and access separate. Tenants share some infrastructure, which lowers costs and makes updates easier. It is common in software-as-a-service applications.
- A tenant is usually a customer organization, not an individual user.
- Tenants may share database tables or use separate schemas or databases.
- Every request must enforce tenant-specific access to prevent data leaks.
- Resource limits help stop one busy tenant from slowing down others.
What the interviewer checks: The interviewer checks whether you understand shared infrastructure, tenant isolation, and the trade-off between cost and isolation.
Other ways it was asked
- “What is multitenancy in application design?”
- “What is multitenancy, and what is it used for?”
- “What is multi-tenancy in a software system?”

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 System Design 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.
942 interviews, 495 candidates, Oct 2025 to Oct 2026. Updated every month with new interviews.
