Cognizant Sr. Software Engineer interview questions

The interview process was simple and straightforward. I was asked to write a core java program and the interviewer was happy to make a decision on the same. They seem to be in hurry, so only a technical interview was enough.

I got a call informing that you will have your interview tomorrow at 5PM. Interview was done and after 2 days I received a call that you are selected and will schedule your HR round soon. And It's been 1 month, still no update from them.
