A free .NET mock interview you can take right now
This is a free, auto-scored .NET mock interview you take online in the browser. Some people call it a .NET interview simulator, a mock test, or an online .NET quiz - it is all of those: a way to practice real .NET interview questions and answers under interview-style pressure. Pick your topics, set the difficulty to Junior, Mid, or Senior, choose how many questions you want, and answer them one at a time the way a real interviewer would ask them. The moment you finish, you get a score, a pass/fail against the bar for that level, and a per-topic breakdown that shows exactly where you are weak. Everything is free with no signup - the score, the full review with a model answer for every question, the PDF report card, and the shareable result all come with no account and no email.
How the mock interview works
- 1. Build your run. Choose topics (ASP.NET Core Web API, EF Core, LINQ), a difficulty tier, a length of 10, 25, or 50 questions, and Practice or Exam mode.
- 2. Answer one at a time. Practice mode reveals whether you got it right as you go; Exam mode holds all feedback until the end, so it mirrors a real interview.
- 3. Get scored instantly. Every answer is checked against a known-correct answer, so your score and per-topic breakdown appear the second you finish.
What the .NET mock interview covers
The question bank has 110 scenario questions across three topics, each tiered for Junior, Mid, and Senior:
- ASP.NET Core Web API - routing, model binding, middleware order, dependency injection lifetimes, minimal APIs, status codes, and the request pipeline.
- EF Core - change tracking and AsNoTracking, the N+1 problem, migrations in production, concurrency tokens, bulk operations, and query filters.
- LINQ - deferred execution, IQueryable versus IEnumerable, multiple-enumeration traps, the operators, and how queries translate to SQL.
Every question is built from the same bank behind my .NET interview questions series, so the practice here lines up one-to-one with the written guides. When a run exposes a gap, the matching deep-dive is one click away in the prep sidebar.
How .NET interviews actually run in 2026
Most .NET interviews move through a screening round (fundamentals and Web API basics), a deep-dive round (routing, model binding, dependency injection, EF Core, and the request pipeline), and a judgment round (trade-offs and architecture). The questions here are written to train the reasoning each round tests, not to make you memorize definitions, so set the difficulty to the level you are actually interviewing for and use the per-topic breakdown to decide what to study next.
Frequently asked 05 questions
Is the .NET mock interview free?
Yes, completely free with no card and no account. You pick your topics, difficulty, and length, take the run, and get your score, a per-topic breakdown, the full review with a model answer and explanation for every question, a downloadable PDF report card, and a shareable result image - all free and all without signing up.
Do I need to sign up?
No. There is no signup anywhere. You configure a run, answer every question, see your instant score, open the full review with the model answer for each question, download your PDF report card, and share your result - all without an account or an email.
What topics are covered?
Three topics right now: ASP.NET Core Web API (routing, model binding, middleware, dependency injection, minimal APIs, the request pipeline), EF Core (change tracking, N+1, migrations, concurrency, bulk operations, query filters), and LINQ (deferred execution, IQueryable vs IEnumerable, operators, and EF Core translation). That is 110 questions across the three. I am adding more topics like async and system design over time, so more categories will show up in the config screen as I write them.
How is it scored?
You get an instant score the moment you answer the last question, plus a per-topic breakdown so you can see where you are weak. Each question is scored against a known-correct answer. Practice mode reveals whether you got it right as you go; Exam mode holds all feedback until the end so it mirrors a real interview.
Are these real interview questions?
They are built from the same question bank behind my .NET interview questions series, patterned on the kind of questions that actually come up in ASP.NET Core Web API, EF Core, and LINQ interviews. They are not leaked from any company - they are written to test the concepts interviewers keep circling back to, with difficulty tiers for Junior, Mid, and Senior.
