EPAM Systems interview questions

First, I apply as a Frontend, then in some point they put in a interview to work as a fullstack with .NET, when I only have a brief experience with BE, that interview take almost 2 hours, the first 1 and a half hour was to talk about BE and the rest for discuss about FE. After that they put me in another technical interview but this one just FE, was another 1 and half hour of question. All this in the same week. After that they told me that they don't need a FE just right now so they don't going to offer a proposal. The relocation package and salary looks very good. Also looks like a very place to work, but they need to be more clear, if they don't need a FE don't put the people in Fullstack interviews.

Basic questions on Spring framework, Java and J2EE, Javascript. There were multiple rounds for different teams by different domain experts. Interviews mostly happened over telephone. There was no HR rounds which was strange at that time.
