I had 4 rounds of interview, 1- Third party Technical Round 2- EM Technical Round 3- EM US Technical Round 4- HR round. The interview was good, i cleared all rounds of interview and submitted my pre-offer documentation and then the company ghosted me. You are wasting your as well as candidate time. I also did some research on the organisation during pre-offer discussion and found the company does frequent layoffs. So, Please beaware if you are considering this organisation.
