It's a real test
How an interview run works
Each run is a graded mock-interview test where you pick the one or several correct options for each question — just like a live interview, except you set the rules. Here's how it goes:
- 1
Pick your topics
Choose chapters from the C#, .NET, ASP.NET Core, SOLID, Design Patterns, and System Design.
- 2
Choose your developer level
Junior, Middle, or Senior — questions are tuned to match where you are.
- 3
Set the length
Up to 70 questions per run (or 100 on the 10-pack).
- 4
Take the test
Answer each question like a real interview — the run is a graded test, scored automatically.
- 5
Get your report
A full report with your weak & strong points and a model answer + explanation for every question.
