I applied via Company Website and was interviewed in Oct 2024. There were 2 interview rounds.

Round 1 - Aptitude Test 

The aptitude test was hard, with over 70% of people likely to fail. However, by thinking practically and answering seriously, we can pass this round easily. There are 20 questions, but they don't reveal the cut-off marks or our scores. In my opinion, the cut-off may be 15 because I cleared this round and I think I scored 15. This is just my guess, as they didn't tell me my exact score.
