3 steps of interview: 1. With HR 2. Technical interview 3. Interview with product manager First of all, i have been managed to get to the interview from the second time. First time, i though that we've allready deal about skype call, because i did not live at Moscow. Next day, HR send me a message with interview cancellation, because they available only for office interview. Perfect.. The second time I tried a few months later. HR responded very reluctantly, often had to write myself. I've pass all steps without any problems, except for a conversation with one "expert" in algorithms and data structures, who could not properly formulate his thoughts and questions, was constantly confused with the complexities of the algorithm. After that, they offer a salary, which was 60-70% lower than the one indicated in the vacancy. I think they just decided to refuse me this way. Conclusion: You should spend your time on having them interview you all the same. In a technical interview, you must convince the interviewer that he is wrong in some cases. You will be asked to pass a security check before an official offer is made.

Multiple stages, pretty easy, but too much unpractical theory. Live coding was also a part of it. Interviewers were nice and professional. Didn't reach system design. HR was also nice and informal.
