recruiter call, then TPS and then onsite. An interviewer called me, she was a young interviewer (i could tell she is inexperienced, the way she was asking me questions on my implementation). Anyways, she asked me to implement a DFS related question and I asked for some clarification by asking some examples. Once I got clarification, I implemented the solution. It was quick. I was still left with 20 minutes. At that time, she mentioned since we are done early do you have any questions for me? I asked her about the role and in the general company's culture. She was not sure about work or vision (surprisingly she didn't know what company's road map is). We ended up the call after a brief chat. Next week I heard from the recruiter that I didn't meet their technical bar. I was like WTF, she was incompetent. I just hope Pinterest improves their interviewer quality. Google and other big companies don't let any incompetent conduct interviews.
