EPAM Systems interview questions

Simple questions and mostly focused on coding and puzzles. Coding questions was Move Zeros to end in O(1) without extra space. And the puzzle question was how to find the unique ball from 8 balls which weigh same except the unique one in less number of attempts.

4 rounds. HR was kind and supportive. 1) Technical Assessment which include AI/ML/Deep Learning Questions 2) Technical round with senior Data scientist from India. Interviewer was very friendly. Deep technical discussion on AI/ML projects, concepts on the same with DL & Gen AI questions. Asked python code from leetcode 3) Technical round with Data Scientist with interviewer from outside India. Kind of same technical questions mentioned in round 2. Asked python code from leetcode. 4) Bad experience. Managerial round with manager from India. Asked little bit of technical questions and some cultural fit questions. He was unprofessional and was expecting candidate should have knowledge like Google employee. He took an interview like in anyways he wants to reject the candidate. In short, had good experience with first 3 rounds. Only had bad experience with Managerial round. Not because he rejected me. It is because of his unprofessionalism, lack of knowledge on how to evaluate candidate as per their experience and wasting candidate's time.
