Cognizant Technical Support interview questions

I attended a walkin interview for tech support at cognizant, there are 3 rounds but wait time was too long Nearly half a day we waited for one round, After they did a second round of interview but they told us that you will receive a mail. But still there is no mail from that team

after the written test, if u crack it then you are redirected to technical interview then HR. The written has aptitude mcqs. in the technical interview focus is on technical aspects and job role.
