Usually interview on EPAM consists of few stages. EPAM is consulting firm and we mostly hire people to work on other large companies like Google, Microsoft, etc. First interview is usually with recruiting and not very useful. Second interview is technical screening interview. Usually performed by some Lead person. Interview is not very complicated. We have only 60-90 minutes, so we could not go really deep. Instead we are trying to cover wide area to understand approximate level of the interviewee. In some cases second interview may be requested. Mostly that happens when interviewee mentioned some specific tools/technologies.
