Participated in an on-campus interview for a 30-minute technical interview. I was asked to find the first duplicated character in a string. Moved on to the on-site interview in Pleasanton, there were 5 rounds of interviews, 4 technical and 1 informal where we asked members of Generation Workday (basically a group of fresh college grads working there) about anything we wanted to know about Workday. Each technical interview was 45-minutes long and one-on-one. They asked me string questions, array questions, tree search questions. Generally everything wasn't too bad, and they're very helpful with hints. It was only the last question that really stumped me because I was never asked something like that -- I've placed it as the one interview question I had below. Advice: Go over DFS, BFS, string, and array problems.
