Onsite interview was with 5 teams and all of them were coding questions. standard C questions on linked list, function pointers, priority inversion and so on. One guy asked Math puzzles, I struggled a bit after constant coding. But i picked up towards the end

Three weeks after applying, I was invited to a 30-minute screening interview for this Friday. However, only 20 minutes before the scheduled start time, they requested to reschedule to Monday.
