It was a 15 min presentation (with pre-prepared slides) on a previous project with 10 minutes of questions. Then a short technical interview on C with fundamental questions on pointers and such.

I applied through my university. We had 3 rounds. The first round being a screening test in which they asked some technical and aptitude questions. After getting shortlisted, the second round is a technical interview round. We were divided into different panels based on roles. The interview questions were easy but I couldn't get through it. The third round was HR round.
