The process took 4 weeks. I interviewed at Cognizant in Apr 2020
Interview
I applied on their career website. I got a mail from a HR. Followed by an HR screening and salary expectations. Then I had 2 technical interviews one with operations and one with someone from the team.
I applied through an employee referral. The process took 1+ week. I interviewed at Cognizant (Atlanta, GA) in Nov 2017
Interview
Quite easy technical round and then client interview followed by HR round. Technical is quite easy but it depends on interviewer . HR you need to bargain for better salary.
