There were 3 rounds. 1. Online Test (Aptitude + Technical + Coding). 2. Technical Round 1 (TR1). 3 TR2 + HR. Aptitude & technical was quite easy. Coding was difficult for me as in one of the questions they asked to write SHELL script and I don't have any knowledge of it. I wrote Java code; it was of medium difficulty level. Out of the total of 55 candidates, they shortlisted only 17 for TR1. TR1 was of medium difficulty. It was conducted for about 40 minutes. After TR1 only 3 candidates were shortlisted for TR2 + HR. TR2 + HR was also of medium difficulty. Again, it lasted for about 40 minutes. They asked everything about Project and UNIX. Suggestion: Prepare your project in detail or else you should have excellent UNIX, SHELL scripting skills, or be able to communicate proficiently.
