There were two rounds, and they picked insane dates to interview me. First round was during my final exam period, and second round was one day after my last exam. I was stressed out and I didn't feel well prepared. Everything else was alright. First round was a video interview with HR. He asked some simple question on C and the others about past projects. Then there was an IQ quiz packed with questions with a time limit of 30 minutes and I failed to finish it. The second round was OK, they asked everything based on past projects.
