Prism Skylabs interview questions

After the recruiter call, had an initial phone screen. The interviewer went over basic questions on vision and ml ranging from traditional vision all the way to deep learning. Discussed concepts like accuracy, precision, recall, specificity etc. Finally asked me to describe an algorithm to construct binary tree from two traversals. No actual coding in this round. Next, there was a 1 hour coding test. I incorrectly read it as finding count of k element subsets that add up to target sum. They wanted the actual subsets not just count. Got a rejection email next day.

They send me some questions through my email to answer in one hour time limit. Not scripting questions but some scenarios where you need to do some troubleshooting. Then a phone interview, followed by an onsite. They want to see how you approach to problems and your way of thinking. It was one of my best interview experience.
