I recently attended an interview with EPAM, and while I appreciate the opportunity to showcase my skills, the experience left me feeling quite disheartened.
During the discussion, the interviewer focused heavily on my career progression, particularly on my transition across technologies and my leadership roles. Comments were made implying that my recent promotion might have been due to solely to managing people rather than my technical contributions. This feedback not only felt dismissive but also undervalued the effort and skills I've put into my professional journey.
While I understand that interviews are meant to access candidates thoroughly, I believe constructive feedback should encourage candidates to improve, not leave them questioning their capabilities or career choices.
Overall, this experience has been a learning moment for me. I hope that EPAM considers ways to make the interview process more balanced and positive for future candidates., regardless of the outcome.
