Average Positive Bengaluru

I found the process moderately challenging, but overall it felt transparent and well-designed. What stood out most was that it included face-to-face interactions and a hackathon-style element as part of the interview flow. That combination made it more engaging than a purely question-and-answer setup.

Even with the difficulty landing in the moderate-to-high range, I felt like the structure helped me understand what they were looking for. The in-person format pushed me to think and communicate in real time rather than just present a static answer.
