After a recruiter discussion, I moved into a multi-round loop that felt very structured: a coding-focused technical round, then two additional technical rounds, and finally an HR discussion. The technical rounds were built around a mix of day-to-day engineering fundamentals and deeper language concepts. I was asked whether I had experience with both .NET and Angular, and I talked through how I write test cases in Angular.

The programming portion leaned beyond just algorithms. I had to write example code for custom middleware in .NET Core, then produce a backend extension method in C# as well. On the SQL side, I remember a “students/marks” style scenario: identify students who did not appear in the English exam, and then rewrite the same idea using an alternative query approach. I also got hit with conceptual questions like the closure concept in .NET/TypeScript, and the differences between events and delegates, including writing code to declare an event.

My process started with a quick phone screen where they basically confirmed I was ready to continue and asked a few basics about myself and the tech stack I used most. After that, I had a longer interview slot that split evenly into behavioral and technical halves. In the behavioral part, I walked through my resume and got prompted with “tell me about a time” style questions focused on how I worked and how I handled problem situations.

For the technical part, the interview felt deliberately manageable: it was an easy-to-medium LeetCode-style coding question, and I remember it being similar to a known linked-list problem. The second interviewer joined for a shorter technical segment where we covered object-oriented programming terms and I was asked to do some light pseudo-code work while thinking out loud.
