I had two rounds. The first one was a simpler problem solving round where I was given a json file to parse and print it's children until it reaches the end. It was a simple recursive solution. The second round was when I realised I didn't want to work here. The person interviewing asked me to design a database for a telecom company to generate monthly bill. He didn't want any interaction at all just me designing. The requirements weren't clear so I designed a simple database without much complications. Now when the review round came in, he was all over telling me how many things were wrong. He hadn't even mentioned those requirements but he wanted them there. The person instead of telling me more requirements was more interested in finding my mistakes.
