Hello friends!!!!!!!

This is Pawan Agarwal. I was opted in MBT (TechMahindra) on 07/05/2006 through campus interview. I am a learner of third year in the department of Applied Electronics and Instrumentation Engineering in Siliguri Institute of Technology.

I am going to tell you about the ques. asked in the interview round (technical and personal). Before that let me tell u about the aptitude test.

There were five sections- three on English and one every on verbal and non-verbal ability. In total there were 70 ques. to be answered in 60 mins. There were no negative marking & still u have to be very fast. The test was online.

For the English parts there were ques. mainly related to tenses, voices and general English usage. It was very easy but tricky.

Then were at lowest 6-7 puzzles from Shakuntala Devi together with series completion (tough 1 & time consuming) and quantitative aptitude.

So go through Shakuntala Devi, R.S. Agarwal, Arun Sharma and Muhammad Muneer at lowest 9-10 times.
