Hopper interview questions

no introductory call about the company or role. was given an online HackerRank problem that I had to use Java for. After that it went straight to a phone tech screen. I was interviewed by a developer who was a majored in linguistics. He was silent during coding problem not much of any feedback. I eventually worked though the problem and missed a edge case but still finished. got rejected next day. I would avoid interviewing here its a waste of time
