5 coding questions in 45 mins ...very easy questions, you can easily do..pen paper based exam. Programs were on strings, arrays and patterns

Round 2 is also coding test here questions were moderate. 3 questions given for 1.5 hours..
Again string and pattern programs were given.
Candidate should be clear with loops , strings arrays..thats it.. no need of studying linked lists ,stacks, queues or other data structures..your knowledge of algorithms doesnt matter here..its all about patterns, strings, arrays and loops

It is last coding round..here there is too much politics those who are working there call there friends and make them sit directly in final round..3 questions given no limit on time you have to do any 2 . They will roam around in roam and will discuss your code..they will help there friends as i was there without any referral there was noone for me..but it doesn't matter if u have strong basics u can crack it ..because problems are again on strings, arrays,patterns . I got bored doing same problems.
