Attended campus career fair on early Feb, had some talks and submitted resume. After 1and1/2 month later, received an email asking transcripts for consideration. A week later, received an email asking scheduling a phone interview. A few days later, had a phone interview. It took about 25 minutes and consisted of four problems regarding high school level math like geometry and sequence. One of them was a little bit more tricky and actually couldn't anser at the moment : four digit number is some multiple of its own in reversed order. Just said strategy. About a month later (late April), received an email asking on-site interview. Had an on-site interview on June. It took about 2hours: HR person and VP. VP asked general questions about my background, current research topic, one basic question on my major, one a little difficult math problem and one puzzle-like question. The math problem was solving some situation which is reduced to basically cubic equation. After about 2 weeks, received a no-offer letter. The company looked nice. People were kind and friendly.
