EPAM Systems Senior Quality Assurance Engineer interview questions

There were 2 Technical round then manager round and finally Bartender round . After that there was a HR discussion for the salary . Finally got the rejection mail from the company

Applied online through email referral. Got a call from HR within 2 hours. Arrogant voice, no sign of cooperation over the call, presented a new question before even finishing the previous's answer, and then came the final question - "What is Epam Systems"? My answer: "A market leader in software solution services". HR: "Of course, it's either a product-based or service-based company, what else?" Me: "I am unable to understand what you are expecting as an answer." HR: "Alright, if your profile gets selected you will get a call from us." He literally hung up before even I could say "Thank you for your time".
