Started from school career fair, I was selected to attend an on campus interview. 2 weeks later, I received an email saying that they would move me to Seattle for an onsite interview.
On-site interview took a day long with 4 interviews, starting at 9:00 and ending at 1:00pm. After lunch, I was informed that I was offered an SDE intern position.
Overall, the questions were not so hard. However, you should show how would you attack the problem. Interviewers knew that questions were posted online and they not only expect you a correct answer, but also your thoughts/understandings.
Be prepared with algorithms and data structures.
