A recruiter reached out to me in LinkedIn and setup a phone interview. There were 2 persons 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 jumped onto 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 a very generalized info 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 bit difficult challenge but he couldn't really explain to me clearly and hence I didn't understand what exactly he wanted. But 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.
