I applied through a recruiter. The process took 3 weeks. I interviewed at Booking.com (Amsterdam) in Aug 2021
Interview
there were very few stages, some of them are: an online quiz, a talk with a hiring manager. from my point of view the process was not very much focused on the technical part, rather they try to make an overall impression of you as a candidate.
