One HR phone interview, one technical phone interview, and 3 round onsite interviews. Such a great interviewing experience and the people are awsome. They take every candidate seriously. HRs are very responsive. San Diego office is big and nice. The package is competitive. They offer tons of events every week and you can always find someone shares the same interest with you. Highly recommend this company and I believe this is the best place to work in San Diego Area. Interview questions are not hard as long as you do well in school.
