Applied directly through my university career site. Got my resume shortlisted and then scheduled a video interview which was done by 3rd party site called karat. The interview went really good. He went through my resume and asked me which was my most challenging project. After that, gave me a coding problem. I solved it in fair amount of time. He asked me time complexity and space complexity of my solution. I told him all the correct solutions. After that he told me there is more than 10 mins left so he gave me a more challenging problem. As I was doing it and was almost done with it, he told me the time is finished and then he went through my code. Told me I was on the right path. I was more than satisfied and really though I would get a call for on site interview. Instead got a rejection after 18 hours through email. Really disappointed.
