They asked questions related to your technology background and previous projects you have worked on. There were three rounds. First one was telephonic. After that technical discussion and at last hr discussion.

DON'T WASTE YOUR TIME. They had contacted me for a freelance opp. that I can do along with my job. I gave 4 rounds of interviews & guess what, they just ghosted me. The recruiter is not receiving calls and not responding to emails. The company is nothing but a scam.
