A recruiter reached out to me on LinkedIn and set up a phone interview. There were two people on the phone call during the interview.

First, I was asked to talk about myself and a specific feature that I developed at my current work. Then, I moved on to the coding problem on CoderPad.

I didn't like the attitude or the vibe that I got from the interviewers (only one person was talking to me on the phone). At the end, when I was asking questions about FB, he gave me very generalized information and didn't really show any enthusiasm, which right away made me figure out that he wasn't happy.

Also, during the interview, I think he wanted to give me a difficult challenge, but he couldn't explain it clearly to me, and hence I didn't understand what exactly he wanted.

On the other hand, the recruiter was outstanding. She called me twice before the interview and reviewed the practice that I was doing for the interview. Even after the interview, she called me and explained to me the result and possible things which I could work on for next time.

Design and write code for a queue system.

This system would include operations such as enqueue and dequeue.
