Totally 3 rounds of hiring process. Got a call from consultancy asking about my work experience and everything.. After a week later Epsilon hr team connected to me and scheduled a interview. It was a bridge call and it went well and got a positive feedback and 2nd technical screening round happened after a month or so with the team in US. And next day got a feedback and asked me to come down to the office for a managerial and hr round. After that in 2 days offer was released.
