BengaluruPosted Mar 2026 · Candidate report, summarized by Dataford

My interview leaned toward frontend and backend-adjacent web concepts.

I was asked questions on .NET, JWT authentication, and Angular routing, along with JavaScript closure behavior and OOPs in C#.

There was also a more hands-on coding style prompt where I had to check whether an array was sorted, which made the session feel like it combined theory checks with practical logic.

The difficulty felt average, and the interviewer focused on making sure I understood the concepts behind the implementation. I didn’t receive an offer, and my reflection was that the breadth across frameworks and language features made it easy to be overconfident about just one area.
