Initial interview was not bad, focused on different architectures and approaches to them. Told me I did well after that interview. They asked me to do a homework assignment, which I put a lot of time into (perhaps my mistake), however there was never any follow up interview. Was left with long periods of no update until finally they told me after I asked for another status update that they had decided to go with another individual. No feedback, no indication of what could be improved. Left me with a pretty bad taste in my mouth.
