Nothing special, basic manager round with some STAR format behavioural questions.

FInal Verdit: Reject for IC4, Hire for IC3 (Feedback was, The interviewer Felt i had not mentored anyone in the past, Which was not the case actually. What i feel the questions interviewer asked were about the approach to solving a problem, Not about my experience as a senior dev in the past.)
