It was an informal 1-hour skype technical interview with coding (JS) tasks. Interviewer asked 3 questions, online code editor was used. No offer. Mostly because I was unaware of algorithmic questions - thanks to "not-really-in-it" HR from recruiting company. So as an advice - improve your knowledge of algorithms and data structures before you apply.

Pretty smooth process, started with talking to HR and passing some questionnaire, then a average technical interview and then interview with the team which I was about to work with.
