I applied through a recruiter. The process took 4 weeks. I interviewed at Ontic (Noida) in Jul 2021
Interview
3 - 4 interviews
Difficulty level - Medium
Ask many things from security domain though this is something which you can learn on the go.
The bad part is they don't give any feedback they took 3 interviews and till a month there was no reply such an unprofessional behaviour.
I would recommend to stay away.
