Snap Software Engineer(Internship) interview questions

I contacted a recruiter and finally set an interview 2 weeks after initial contact. There are two technical rounds. For the first one; it was a live coding interview on hackerrank.

Was contacted by a recruiter and scheduled an initial technical screen via Google Hangouts, which went super smoothly. Interviewer was prompt, professional, and I made it to the next round. The second technical screen was a nightmare. I was greeted with two engineers and the first immediately let me know that the second one was in training, but would be conducting the majority of the interview. The first interviewer proceeded to visibly play on his phone throughout the entire hour. The second interviewer had clearly never interviewed someone before, leading to him whispering to the first interviewer in front of me, saying "sorry, I can't give you any hints, because I can't describe it without giving the whole question away," and smirking every time I attempted to clarify something about the question, which was confusing and vague. The second interviewer couldn't even walk me through an example of what the algorithm was supposed to do until the first interviewer intervened. Overall, I was pretty disgusted by how unprofessional the interviewers were and what a massive waste of time this was for me.
