The first round of interviews was primarily knowledge based with some behavioral/personality questions mixed in. This took place on my college campus.
The second round of interviews took place at Telligen's HQ in West Des Moines. The interview process lasted about two hours and consisted of three different stages: group, coding, and a tour. The coding interview was the bulk of the interview process; however, it was very short and direct. There were some basic "coding on white boarding" questions and language knowledge questions. There were not any special algorithm design questions or any puzzles.
