Spotify Summer, Backend interview questions

Applied online in December and interviewed in February. The interview was mainly focused on technical knowledge, with whiteboard coding and a quiz about CS fundamentals. The interview itself was quite ok, I don't have much to add. One of my main criticisms is that I never received any rejection email. Since they told me they did only interview about 5-6 other persons for the role, I think it would not have been that difficult to send one, it is always good manners to thank an applicant for their interest in the company and the time they spent interviewing with staff. :) Don't leave them hanging.
