EPAM Systems Data Scientist interview questions

An average general interview throughout for the KL, Malaysia office. What pissed me off is the follow up. Towards the end of the interview, I was told that there would be an online test and I would receive the invitation by end of the day. 3 working days passed and no news or update. I contacted one of the recruiter to ask for an update, and the feedback I received was "XXX recruiter just attended project meeting today & got an update from the hiring team that the requirements have been changed. At the moment, we need someone at Senior (5+ y.o.e) & Lead level only." People are not as foolish as you believe them to be. Firstly, you were saying that the hiring managers changed the requirements in a meeting 3 working days later yet I was supposed to receive the test way before that. Did you mean to say you were already aware of it way before but didn't care enough to update? Secondly, the job posting is still up on their website. It is fine to reject a candidate, but please do it professionally and try not to lie about it, and certainly do not promise anything if you're unsure. Both your and my time are valuable so please don't waste them.

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.
