Screening interview with the CEO went very smoothly. We talked about my goals in applying to Soramitsu and about the company. Although I was doubting if I wanted to work on a blockchain project, after this interview I became much more certain that I do.
Technical interview was quite challenging, with questions about algorithms, C++, software design and one live coding task. Interviewers were respectful and professional, I learned some things at that interview from them and definitely wanted to have such colleagues.
