Cognizant Sr. Software Engineer interview questions

Easy and good. 2 technical and 1 HR round. The process was spread through tout the day including a lot of waiting. But overall happy to walk out with satisfaction .

2 technical rounds followed by HR discussion. Initially HR called me she took all information about me including notice period, after that scheduled 1st round of technical interview. I finished and after 2 days got call from same HR and she told you cleared interview and again she asked for noticed period details. After that no response. If notice period is the concern why they scheduled interview with me.
