I applied online. I interviewed at Cognizant (Chennai) in June 2026
Interview
only one round of technical interview for senior position, and hr execution was not proper, they didn;t connect when needed and no proper negotiation of salary either since shortlisting for interview
The interview was primarily technical, concentrating on C#, .NET, SQL, and API concepts. Questions tested understanding of core principles and practical application. The process was straightforward, professional, and focused on technical depth.
I applied online and got a calll back, had 4 rounds in total. first was a behavioral phone call just casual talks about your skills and when can you start working and general questions, then two coding rounds in hackerrank - was asked to code in java although the job was for python and finally HR.
