Pieces Technologies interview questions

1st Round :: Google Hangout Interview The dude showed up to the interview, and started asking me about Angular, I told him that I've no Angular experience, and he didn't take it nicely, he asked me about my experience without any follow question, and suddenly he threw a question on the chat and asked me about the output, I've to admit that I answered the question wrong, but part of it was related to the not-welcoming space the dude created, he's definitely didn't what he was doing, his interviewing skills are almost zero, I interviewed a lot of people in the last couple of years, and my team and I always focused on what candidate knows, and we walked them through the problem, also discussed the possible solutions with them. The second question was an algorithm question, according to their email and I'm pasting what they sent to me "Feel free to think out loud, this helps us understand how you have broken the problem down. It doesn’t matter whether it’s correct path or the incorrect one" So I took their words seriously, and tried to engage the dude in the solution process, I gave him 2 solutions for the problem and explained the complexity of each solution, and he literally said "you are supposed to figure it out" , I told him that if we were working as a team, I would ask him for his feedback, he didn't like that, he didn't like that I was asking him question, he wanted to sit down and watch. The interview told it all about their environment in the company.

There were two phone interviews. Both of them involved coding (Google Hangouts) using IDE / Editor / Language of your choice. Then, I was invited to on-site interview at Dallas. The on-site interview had four rounds (Mostly 2-3 whiteboard coding problems). The problems were mostly on backtracking and basic DS. I managed to arrive at decent solutions for most of them. The development team were very friendly and professional. The last round was with company's CTO. He seemed very amiable and knowledgeable. But, by the end of day, I was mentally exhausted and couldn't do well on some basic stuff. Overall, the process took around one month but it was totally worth it as I got to talk with some really professional people who seemed to know what they are doing.
