      Interview Experience
      There were 4 rounds of interviews...
      the details are as follows
      Interview 1 - This interview was basically DS based interview and certain concepts of networking were touched. I
      told them that i am interested in data structures and cryptography so most of the questions came from those areas only.
      Interview 2 - Was again technical. The interviewer asked me on Data Structures and a Dynamic Programming problem and some other puzzles to solve.
      Interview 3 - This was technical but they evaluated the design skills. Asked me on ER diagrams, class diagrams and
      database design and system design and some basic questions from OS. 
      Interview 4 - This was also a technical interview mainly on problem solving and DS design (how would you design a DS to handle this situation and so on).

          Test Sections
          • Section 1: ONLINE TEST
          Interview Experience
          Screening by an online round containing programming and multiple choice questions. Selected candidates (25 approx.) had four technical interviews wherein approx. 5 candidates were eliminated in each round. 4 students were offered a job.
          Interview Tips
          Online Programming Contests in spoj,Codechef,topcoder,Codeforces, Hackerrank,Hackerearth, Project Euler.
          General Tips
          Make sure the interviewer knows what you're thinking as you solve the problem. Don't just come up with the final answer. Prepare on algorithms and Data structures.

          It was very exhausting as the interviews went up to 3 a.m in the morning. It was compensated by very interesting and new questions.
