Initially there was Written and then 2 technical interview rounds, one with an engineer and another one with the manager . Finally there was an HR round. It was a 2 day process.

I applied through my college. An online test was conducted in our college on firstnaukri.com platform. It consisted of three sets. One was of aptitude questions(easy to medium level), one was of technical questions(MCQs on Java, C, C++, C#) and the last one was coding round which consisted of three questions( 1: print prime numbers between 1 to n, 2: Print coordinates of saddle points in a 2d array, 3: It was a dynamic programming question, I don't remember it). Time allotted for MCQs was 1 hour and for coding 50 minutes. Then after 2 weeks around shortlisted candidates were informed about the date of interview. The interview was supposed to be at Noida office of NEC Technologies. There, interviewers were very cooperative and friendly. Technical interview was carried out more than 1 hour and after that, there was an HR round. Some candidates were supposed to give 2 technical interviews(If the employer was not satisfied with their result in 1st technical interview round).
