I only had a short AI-based screening round. It was a video interview where a bot asked questions directly to me, and it lasted around 10 minutes.

The environment details mattered—they requested specific setup: good lighting so my face was clearly visible, a clean background, and the camera at eye level. It also only allowed a single attempt, so once the recording started there wasn’t any room to redo it.

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.
