Axon Senior Software Engineer interview questions

The interviewers were very nice. I got an email after completing five rounds that they are not interested in moving forward. I asked the HR for feedback but i did not get any response. After spending 5 hours with them, don't i deserve a feedback?

I had a phone conversation with a director after he reached out to me online. This was followed by a conversation with an internal recruiter/HR. Out of this I got a good idea of what the technical interview would be like. Then I had a one-hour technical interview made up of: 10-15 minutes of going over work background and projects, a 30-35 minute coding challenge, and then wrap-up questions from me to the interviewer. The interviewer was not familiar with the area that I'd be working in and the questions were a little more oriented to back-end or desktop than embedded, which is what the role I interviewed for would focus on.
