I was called in for a pooled campus drive at a college in Kolkata. It was for BCA/BSc Comp Sc. graduates exclusive drive. A 45 minutes Pre-placement talk was held, after that the Aptitude session began. This was a aptitude of moderate difficulty. There were 3 sections- English(also Analytical Reasoning), Quants(basic P/L, Speed Distance Time, Ratio, Average Percentage etc), E-mail writing. I cleared the aptitude, and then began the Interview. Due to shortage of time, the Techincal+HR sessions happened at once. The interviewer was a nice bloke. It went on for 40 minutes. Basic programming concepts,DBMS concepts, minor+major projects discussion, family background, location constraints etc were the main highlights of the interview.
Overall the interview experience was good, I got the Letter of Intent within a week. But the sad part is I got the joining letter after a year. I didn't join because by that time, I had already enrolled myself for post-graduation.
