EPAM Systems Software Developer Sr interview questions

Began with an email and basic phone screen, with a lot of attention to detail towards scheduling, etc. I was told a technical interview call would be about 45 minutes, and the actual call came in closer to 2 and a half hours. Despite that, the interviewer was professional if somewhat hard to understand at times, with a wide range of questions and one programming challenge related to general web development. No contact whatsoever after the technical interview, making it a complete waste of my time.
