ExpertVoice Senior Software Engineer interview questions

I was contacted by their HR and a phone screen was setup with the VP. The phone screen went well and I was brought on-site for an interview loop with the rest of the team. I was scheduled to interview with about 5 people, including the VP and the CTO. The first 3 interviews went really well with the devs. But, when it came time to do the design interview with the VP, things went south really fast. He became irritated when I couldn't figure out a particular part of the problem and it made me very uncomfortable. Because of that, I became discouraged and couldn't wait for his session to end. In the end, he became disinterested and started answering texts/emails on his phone. Shortly thereafter, he told me he was the last person I'd be interviewing (even though I still had the CTO to meet but I got the hint) and led me to the door. I was happy to leave early! I got a call from the HR the following week explaining that she was still waiting to get feedback from everyone but the preliminary response was positive. That was the last time I ever heard from them even after sending a follow-up email. In the end, I'm glad I wasn't contacted because I would have rejected any offer. After my experience with the VP I knew this would be a toxic environment to work in.
