I applied via referral. The whole process took 6 weeks, no offer. In the end they provide me feedback about my interviews, which is a huge plus. 1. Homework assigment for 1 hour, matrix-traversing. Easy, but you need to provide clean code. 2. Talk with HR. Just check if I can speak English and some formal details 3. Techinical phone interview. Algorithm + system design. 4. Skype interview with 2 different devs. Interview, code session, interview Questions were interesting and various. They were closer to real work. For example: "Imagine that I work in frontend and you need to provide me api as you work in backend". I enjoy the whole applying process, responses were quick, HRs were nice. Process last long cause of New Year holidays.
