Rotational Analyst test was on SHL platform for my batch. It comprised of basic aptitude questions(logical reasoning and quants ), technical questions on networking and operating systems. Usually , there used to be three interview rounds ( technical, case study and ION day). However this year(2022) the hiring process changed a little and technical and case study round was clubbed. It was completely on interviewer if he asks case study or technical questions. (CS/IT branch is always preferred) This was followed by ION day which was the final round.
