FiveRivers Technologies Senior Python Developer interview questions

I was contacted via LinkedIn for the senior python developer position at FiveRivers Technologies in May 2021. After the HR call, I was invited for the technical interview. The interview lasted for 1 hour. After that, I never got feedback on it. I tried to follow up multiple times via email but no reply from the HR management. The poor interview process with the non-professional behaviour. Won't recommend it to anyone.
