First round is HR phone screen. Everything goes well (at least I think), the HR is nice. And I was told that I will received a case interview with the manager (as she said I am doing very well). However, after one week, I receive an email that I cannot get the offer. Well, ok.

there are resume screening, on-campus one-hour interview and on-site full-day interview overall, the interview requires a well-round skillset including coding, stats, problem solving and soft skills people are nice during the interview process have the chance to meet the head after the interview
