Tinder Software Engineer interview questions

I applied online, and the recruitment coordinator contacted me 2 days later. We had a casual first phone interview, after which, she immediately scheduled a technical interview with me in 3-4 days. Up to this point, it all went very well. The technical interview was the turning point... It lasted about 50 minutes. Not only the interviewer was in an open space with a lot of background noises, but he also had an accent. Almost half of the time was spent on me asking "what?", "say that again?", "sorry, I can't hear you..." and him repeating. All in all, it felt like they didn't plan the interview ahead of time. Very unprofessional.

I was recommended through a friend and emailed the recruiter. Then I was set up with a phone screening with a software engineering lead and was asked very basic questions. They were mainly behavioral questions with a smudge of technical questions. I really thought I did well but I got a rejection letter the day after. Even provided that I have Android experience under my belt, I really don't know what they expect from interns to even consider them.
