It was a 3 step process in which we had a normal online test of aptitude which included some questions related to quants, logic, and english.
After that it was a coding round which had 3 questions to be done in any of our preferred language. They were of a normal level and not too difficult.
After that it was a final technical round in which interviewer was a cool person and he asked some basics of oops and 2 codes to be written in front of him just as a purpose of checking our problem solving.
After each round shortlisting was done and finally out of 100 student around 15 were selected.
Overall it was a easy process.. Which took a day.
