Applied online, within 1-2 days got an answer from HR telling that they liked my CV and wanted to go forward with the process. Had a coding challenge at home, passed then had my personal interview. I liked a lot to be honest. In the office I had a chat with about 5-6 people, first with the Recruiter, second with two guys which asked me things related to architecture, third a SQL challenge (which I failed - honestly it's been at least 6 years I don't work with SQL, just NoSQL) and finally with a manager. Despite the SQL, which was the only remote challenge, (also the call was very bad and I couldn't hear the interviewers properly) I really liked the company and I think their hiring process is good, people seems to be very smart and they respond quickly when you submit questions/enquiries through e-mail. I recommend this company for everyone.
