Zenput Software Engineer interview questions

This was a really bizarre process. Instead of a recruiter, I spoke to someone really high up in the company (equivalent title to C-level manager at other companies I've worked at). We both agreed on a time in writing. I was sent a calendar invite (with the agreed upon time) that I accepted. The interview began late, and I was told that we supposedly never agreed on a starting time. I heard a lot about other companies in this time, and I couldn't get an answer on what the company was doing technically. I never got a chance to explain what I could do because the interview ended early. After a few days, I got an email that said even though I had an impressive background, my skillset supposedly didn't match. It also read that the timing for me to work at the company was just bad (since I had other interviews), so I just probably wouldn't ever be able to work there.
