After the 2nd round of interview, when can one expect the PPO offer or a line of communication from HR?
Do they reject the candidate after the 2nd round?

What questions did they ask

1st round was technical and 2nd round was just a conversational interview with the partner.

Which batch are you from? And which team was this?

Congratulations on the PPO! Party faad

No. Only those who were approved in the first round make it to the second round. It's guaranteed that you will get a PPO at this stage. You should hear back within a week.

Seconded. The second round is only a formality - the first stage is when you could be rejected. It could take ages for the HR to confirm after either round.

I was rejected in second round.

Batch of 2022?
