first round was written test which is quite simple. But, the shortlist was made by sectional wise cutoff marks. so one never expect that it has 3 sections (aptitude, critical thinking, technical) because before the test we were informed as only 2 sections (aptitude, technical) . so we may commit mistake by answering only few questions in critical reasoning and thinking that this section will be covered in aptitude itself. so we might be disqualified.
