I had a phone interview and one week later another online peer programming session was scheduled. After peer programming, I got a rejection. I was able to solve the algorithm question he was asking, also without any hints or help. I still got a rejection. Asked for feedback about why, and I just got the usual recruiting email back. Very bad experience, as I said I got everything done correctly. Don't know what they're looking for at Poshmark. A waste of time!!

30 minutes phone call interview. The iOS leader interviewed me. Very simple algorithm question, writing code on coderpad. Unfortunately, I blew it. He asked me write the code with Objective-C, god, I never do algorithm with OC before. I know how to solve the problem, but I can not write code in OC in a short time. Even worse, I wrote OC function in a wrong format. OMG, I am a iOS developer, how can I make this low level mistake. So the interview ended at first question 15 minutes later. Mad myself.
