Was contacted for a phone interview.

Recruiter seemed nice enough, but his whole demeanor changed after he asked me if I was interviewing anywhere else. Obviously I was, so I answered "Yes". After this he asked me, "Is Circle your number 1 choice?". I'd never been asked such a direct question about this before, so I came up with something like "It is definitely one of my top choices."

I was completely ghosted after the phone interview. Now I'm not 100% sure that's why I was ghosted, but the tone of the interview changed after that, and I think it's a strange question to ask. It's as if they're trying to weed out people who aren't 100% their top choice.

Standard phone interview questions included stuff like: "Tell me about yourself." "What are your prior internship experiences?" and "Why do you want to work here?".
