The procss was very smooth, the recruiters are very helpful and they get back to you very quickly. I applied normally through their website. A few weeks later, I get an email that the recruiter wants to talk to me about my background and experience. We went on a call, then a few days later I was invited for the interview.

Also within a few days, I was invited to the final round.
