First I got a phone screen from HR with some routine, general questions about my experiences, background and past. After that they set a 2 hour online video call. the first part (one hour) was called "Life Story" in which I was asked about every detail from my childhood to school years, university, job experiences (related and not-related to my major), my life style and ... the second part was a coding challenge which was really easy. The main focus was that how I would approach the problem, solve it or debug it or solve a problem in case you face one. It was really easy and took only one-third of the designated time. After that I was invited for an on-site interview which had 4 parts - 1 hour each. 2 coding challenge sessions (pair programming), one informal chat with one of their tech-leads during the launch and one deep dive technical session. After all of these I had a half-hour chat with HR again. In pair programmings they brought up a problem and I should write a code from scratch and in the other one they gave me some code and I should contribute to change some parts of the code or add some feature to it. I think the most important focus of the coding challenges was designing, clean codes, debugging, searching on the internet properly in case you need, writing tests for all edge cases and ... It was called pair programming but actually it wasn't pair programming! One of my interviewer barely looked at the codes and he just wanted to see the result, he even didn't answer my questions to clarify the mission thoroughly! So it was a bit of stress for me during the programming part. In Technical Deep Dive session I was asked about my technical responsibilities and contributions and achievements and how I dealt with challenges that I had. I was really satisfied by the deep dive technical session during the interview but after being rejected by the company I got surprised that they gave me the feedback that in some of the cases I was talking generally, not in details. Which really didn't make sense because I could go in more depth in anything if I was asked to! At the end you will get feedback (for each of these sessions) which clarifies why you do not get an offer.
