Rajasthan Studio interview questions

There were two rounds. One assignment round and one interview round. I had to send a work sample first and after they shortlisted me, interview round happened with the HR

They gave us a task to complete. It is the first part of the interview process. I completed the task and send it on given time. But they never reviewed the code or gave and feedback to me. That was a worst experience. If you don't need us why wasting our time.
