Recruited on LinkedIn instead of their careers page.

Had a chat with the recruiter who told me she was building a team, as if she were the hiring manager. I had to sign an NDA before the interview, yet was still told the project was confidential even though I had signed it.

Then, I had an hour-long phone screen, and was rejected 10-15 minutes after the call. The reason given was "not a fit."

The interviewer was very rude and tried to cut me off multiple times when I indicated I was thinking about an answer. He then moved on to the next question, seemingly uncaring or having already made up his mind.

After asking the interviewer how I did, he stated he would have to "look at his notes," which was a clear sign he wasn't interested.

No rejection feedback was given, and emails were not returned.

Easy Android trivia questions were asked, using a hashmap counter that I got correct.

Biggest "kickers" were "Do you even know what asymptotic means? A lot of people don't," which was rude and uncalled for.

He kept asking me scenario questions for some reason, even though I had never researched how to do those things before since I didn't need to in my applications.

Also, there were "stupid questions" like, "Why can't you use primitives in a hashmap?" Who knows? I didn't implement the collections class, so how should I know.
