Got an email telling me to schedule a phone interview. Had the phone interview, and got asked if I would be willing to do an coding challenge. I did the challenge which was an hour and a half and then spend another 45 or so minutes writing up a thinking process as asked. After that I did not hear anything back. Tried pinging them a few times to see where the process is at or to get some feedback. It's been 2 months and no responses.
