First round We had an online aptitude test in our college. It was basically analytical and quantitative.Total there were 40 questions - 40 minutes. It was average kind of difficulty - not very easy. Time management is the key. Analytical - Lots of questions about blood relations, seating arrangements and syllogisms. Quantitative - Questions about speed/distance, profit/loss, train, work/time, 2-3 questions about algebra. About 100 people were selected in this round. Second Round It was a coding round of one hour which had three questions. 1) Divisible primes 2) Given two numbers, find the number of bits which are different in the two numbers. 3) Very easy program. About 60 students were selected. Technical Round Was asked questions about data structures, linked lists, c programming, print a given pattern, operating systems - semaphores, deadlocks. I was not able not answer properly. Did not go to next round. There are two Technical and one HR interview. Though I was from ECE no questions about communications, embedded systems or networks were asked. I guess they were hiring for some software postion. Learn properly data structures, operating systems. Some of the students were asked aptitude, puzzles, maths,etc.
