EPAM Systems Sr. QA Automation Engineer interview questions

Recruiting process consisted of Skype interview with HR, technical interview with senior engineers who asked me about core Java, web and rest api automation. Interviewers were polite and friendly and definitely it was not a hard to pass it. Final interview was held by lead QA in terms of project screening, some decision making questions etc. Offer has been provided soon with quite attractive salary. Unfortunately I could not accept it due to an enormous number of negative feedbacks about the way company works , it's vendor model. That's was frustrating since the project was challenging.
