There were 2 rounds of aptitude tests which include quantitative, grammar, fluid intelligence, coding, algorithms and data structures. There was a psychometric test after the other 2 rounds. On clearing these 3 rounds, you'll be selected as an intern for 3 months and there will be an interview after that to convert you to FTE.
