Noyo API Engineer interview questions

The interview process with Noyo consisted of several rounds of technical interviews. Starting with a 45 min technical background conversation, then a take-home coding challenge, followed by several multi-hour-long interviews with the senior staff. I made it all the way to the end and was told that I would receive an answer from them either way in a short period of time. However, they completely cut off lines of communication and would not respond to any emails or calls. Highly unprofessional and would not be willing to hear an apology either way.
