I applied through a campus event. Two days later, a recruiter contacted me for an initial phone screen. The first interview was typical HR phone screen: why are you interested in the company, previous experience, willingness to relocate, expected salary. Nothing hard. She was reading off my resume. That same day, I received invite for quantitative interview. Second interview as a quantitative interview. Interviewer jumped right in. Three questions mostly about probability and statistics. Lasted 30 min. Received email two days later informing me I didn't advance to the next round.
