Real .NET Interview Questions (2024/2025)

From September to November 2024 I had a “pleasure” of looking for a new programming job as a senior full stack .NET developer. I was dedicated full time to this process as I have still been on a sabbatical break. It took me a bit more than 2 months, during which I submitted around 150 well-crafted applications, took part in 25 full technical recruitment processes and was asked hundreds of .NET interview questions.

In this article, I’m sharing a compiled list of the most popular .NET interview questions I was asked during all those interviews. They represent real questions asked on job interviews for a software developer with almost 10 years of experience. Hope you enjoy it 🙂

If you’re curious about how I’m planning to use these two months without paid work to improve my programming skills (and why I can’t seem to get my productivity back), read on 🙂

In this short article, I will give you my 5 reasons why the backend code editor might not be the best IDE for frontend development 😉

NOTE: calling this post a “rant” is obviously humorous 😉 This article is my own opinion, not a hate on anyone using different IDEs than I do.
