DXY Solutions interview questions

Applied through University job portal. Received a call from hiring manager. The call was to discuss the position and a few general questions on resume. Cleared the first round and got a schedule for second round. Second round was more technical and consisted of solving one problem. Was told that I will be contacted in a week after the second round. The company never replied. I kept sending emails and even called multiple times but no one replies back. It is very bad that they do not even give you a decision.
