I was called for a technical phone interview in which I was asked to write code for a question comparing a few user's total scores and then give each user a competitive rank.

The interviewer asked me to talk through the code as I wrote it. Part of the question involved sorting, and I very honestly told him I didn't remember much about the built-in Java sort. He posted a link to documentation for it, which led to me asking if I was allowed to look up documentation online during the interview. He acted as if I should have known that from the beginning, despite not ever telling me.

It took me about 20 minutes or so to write out a solution, and then he began to ask me questions about it. At one point, he asked me about a function I wrote to compare elements in a list, pointing out that the return type should be different than the one I had. Despite me explaining that the return type I had was correct, which it was, he argued with me until I changed it to the type that he wanted.

At the end of the first question, he asked me if I could improve the solution I had. I explained the best way of doing it that I realized after I finished my first solution. His response to this was telling me, "Yeah, that's how I would have done it the first time around," in a very rude and matter-of-fact kind of tone.

Finally, he asked me another quick question, which involved finding the intersection of two rosters of players. I was just asked to talk through this question and ended up coming up with a solution very quickly.

I asked him what the next steps were in the interview process, and he said they would get back to me within the next two days. They emailed me back 4 hours later, rejecting me with no explanation.

Rank players based on total score in the case that some players tied in score, and find the intersection of two rosters.
