The whole process was of two rounds. The first was an Aptitude round, consisting of basic apti questions (RS Agarwal should be enough to crack this), and also consisted of verbal section. This round is usually adaptive type, so the level of difficulty is variable according to the individuals' performance. The next round was a kind of group interview(2 on 5), there were 2 HRs and 5 candidates. The interview was very generic, most of it was a general discussion on technologies like Internet of Things, AI and ML (again nothing technical, but an overview on these technology). Also there were questions on extra- curricular activities and on hobbies. The interview mostly concentrated on the candidate's confidence in communication rather than on their technical ability and also on the resume, i.e how truthful is your resume, since they were asking questions mostly based out of what was present in the resume. Overall, it does not require much of technical preparation, just if the candidate is well prepared on their resume, the interview should be a cakewalk.
