I applied through college or university. The process took 2 days. I interviewed at Cognizant in Sep 2015
Interview
there were 3 rounds..aptitude, technical and HR...aptitude round was easiest and technical depends upon the prep you have made...mainly consisted of dbms. object oriented programming, any program based on your field of interest..sometimes even micro processors questions are also asked.
Very easy fireside chat. No technical interview. For clients mostly simple coding: reverse a string, anagram, impl linked list, basic sql query etc for associates. For sr and manager it may be more advanced.
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.
3 rounds of interviews with a technical interview. The technical interview involved questions on Java and sql. They were mildly difficult. The first 2 rounds were not so difficult, lots of situational judgement questions
