Very friendly HR contact person. Kind of abrupt hiring manager. He didn't call on time. He seemed like he had a list of 50 people for the job and had to interview them in 2 hours.

Applied online through university recruiting website, interviewed on-site. Four back to back interviews, each on a different topic and with a different person - architecture, design, fit and experience (going through resume), algorithms. Overall a good experience, they had awesome offices and the interviewers were very clear in describing their questions.
