Interview with hiring manager on the phone went well. I was called onsite and interviewed with 5 members of their team. The team members were very friendly and open to talking about their projects and my role. The interview was very technical as expected. They had a written test that was administered early on prior to the interview. A large part of the hiring process is based on the test I think. I thought the interview went well and was told that they would be going ahead with an offer. But, I was later told that the CTO vetoed the offer, which was a bummer because I liked the team and thought my skills lined up well to fit in. Oh well...moving on.
