I applied through college or university. The process took 2 days. I interviewed at EXL Service (Calcutta) in Dec 2017
Interview
In campus interview: one round of aptitude test followed by PI. Two day process . A basic aptitude paper was offered. The PI was mostly around guesstimate. The pi process lasted for about 15-20 mins. A lot of emphasis was around guesstimates and a few common aptitude questions . As a fresher ,preparing for aptitude and going through a few guesstimate problems should be sufficient to impress the interviewer.
Basic type of interview focused on resume and other basic skills like sql . Also they asked puzzles and guesstimates. Interview was very smooth and nice , you don't need to be panick at all just be confident at the time of interview
It is a very lengthy and time consuming interview process. Gaps between the interviews is a little long and it takes the whole day to finish with all rounds of interviews
It was easy and straightforward. There were 2 technical rounds. They asked puzzles and brain teasers. Panel was jovial and helpful. They have hired quite a few people at once
