First of all, the interview process was very systematic and well planned. I felt like they actually cared about my knowledge. They were not aggressive or critical about what I don't know, rather were interested to know about my approach to coding, my goals and what I had to say.
Basically, the entire process consisted of 4 rounds -
1. Aptitude - 25 + 35 min - (2 sections, Quants+LR and SQL). Has sectional cut-off (probably 50%)
2. GD + HR - 15 + 5 minutes - Group is given a topic which is very common like Social Media or poverty in India. HR round was mostly just a formality round which consisted of "are you comfortable of working in shifts or in any role, etc"
Then comes the main 2 rounds. Both are technical rounds.
TR1 - 15 + 30 minutes - was given 3 codes to write in 15 min. Codes are not long/complicated but concept based and twisted. (WAP to execute both if and else statements. WAP to find higher and lower no. without using comparison or conditions. WAP to reverse a number without using strings)
After you write these, you will have a F2F interaction where you will be asked to explain the codes you have written, why you chose the approach, alternative ways, optimization, some modifications. Now the focus will be entirely on your CV and what technical related points you have put in there. If you have mentioned only C, they will ask only about C. But this will be very deep. They will really check your understanding. Not just your knowledge. And everyone was asked SQL queries.
4. TR2 - 35 to 40 minutes -
This will be conducted by a Project Manager. There is not really a constraint about what they will ask about. In my case, we touched a lot of things right from SQL, C/Java, to Software Engineering, Clouds, Data science, AI, ML, recent trends in technologies. Everything was covered in this round. Also, my hobbies, my long term goals, why I set those goals, how will I manage a stressful work life balance.
In all, whoever I interacted with, right from the security to the Project Manager, everyone was super polite and made me feel valued, even if I was just another one of the hundreds they probably interview every day.
