Got a call from employee referral First was a written round . 30 min c/java 45min aptitude Both of the were quite easy and not to forget questions were repeated so look previous year papers. After a week got a call that is was selected an was called for interview on next week. There were 4 rounds that day All the questions were easy . Questions were for testing like testcase for pen, waterflow model, int86 , prime no. programmes , testcase for highway etc/. A lot of puzzels were asked all can be found on internet. Prepare puzzles well. The after a week got a call that their response were positive but the hiring manger wants one more technical round This interview was held next week and similar questions were asked programming and puzzles not to mention you have to code in white board so be prepared. After a week got a call from HR saying I was Selected :)

The complete process involved 1 aptitude round, 1 coding round and 4 face to face technical interviews. The aptitude round questions are all about Maths which you would have learned in school(class 5th-10th). THe test format can be found on different sites. The coding round is through Hackerrank. There were around 20 questions, 17 MCQs and 3 coding questions. The coding questions were pretty easy (pattern printing, array multiplication). The interview was a little tricky though.
