Spotify Project Manager interview questions

had a series of 3 phone calls spread across 3 weeks with another product manager. 1) was a brief call spoke about myself 2) we spoke about Spotify 3) I was given a homework assignment

After a few emails and then a Skype interview with HR in Stockholm, reviewing interview process, team culture and timeframe (expected 3 months for me, American, to be hired into the Stockholm HQ). After the initial screening had 2 more interviews via Skype with the hiring manager. She was very smart, passionate about the space. It seemed like great team and opportunity. Then I was passed to another/different HR dude, who informed me he would be in touch regarding next steps (which would have been the f2f in Stockholm). I got the distinct feeling I was being put on the back burner ... A few weeks later I was told that an offer had indeed been extended to and accepted by another candidate. While the 2nd HR dude expressed interest in me as a candidate for other positions, when I pinged him in the future, he never responded. Oh well.
