posted on 19 Dec 2024
I applied via Campus Placement and was interviewed in Nov 2024. There were 3 interview rounds.
The hardest round I have experienced during interviews was ultimately successful, as I was selected. Only a few questions were multiple-choice; the rest required one-word or numerical answers to be written manually. Pay special attention to the last portion, as it was a scoring section containing standard technical questions. However, as we begin the assessment, the majority of the time is consumed by reasoning, arithmetic, and similar topics. In summary, I can say that the initial part is the toughest.
