Interaxon interview questions

Applied through job posting, had a screening call from a recruiter, then moved on to the first interview which was done via zoom with a VP. Received a voicemail following the video interview saying it went really well and I should hear back in a week. I sent a follow up email after a week- never head from the company again.

I applied online on their website. Was contacted by the HR for phone screening, followed by coding challenge. It was python coding challenge, 4 hours duration. I did not clear the coding challenge.
