Nice and professional. 3 different interviews: introduction, cultural and technical. Everything went really smooth. Met different experts in different interviews. Got a really positive impression of the company and clear vision what they are looking for and what they could offer.

HR -> test assigment (did in few evnings) and it was interesting one -> Tech talk with CTO and Developer -> CEO. Process was actually faster than 3 weeks. All people that I met during interview process were really nice.
