I applied through a recruiter. I interviewed at Equinix (Warsaw, Masovia) in Jan 2020
Interview
Initial screening + two meetings on site (it was before covid): 1st - with future manager of the team, 2nd - strictly technical with two senior members of the team.
Technical part was quite comprehensive and included coding of sample problem.
1. Went through basic JS questions, then code out a simple sorting algorithm
2. Different interviewer, more questions on experience, went through some agile methodology and handling of project communication.
3. Director interview
