There are totally two round interviews. I received the first round of the interview within 24 hours before the interview. The HR asked some basic behavior questions. Easy to answer. Such as the most difficult situation to deal with and your leadership ability. Then after several weeks, I received the second round interview notice via email from one manager. He asked me some basic computer science problems. He was very nice and patient to guide me during the phone interview process. It took about 15 mins. Finally, he asked me about my available time slot to do the intern. Very nice experience.

Interview process is pretty fast. There will be 2 rounds of the interview. first HR will ask you details about your background. It then followed by hiring manager for Technical Interview
