EPAM Systems Sr. Software Engineer interview questions

EPAM Systems initially reached out to me for a role and scheduled a 1.5-hour technical interview. The panel was knowledgeable, and the questions were relevant and engaging. I genuinely enjoyed the technical discussion and felt it was a strong round. However, the overall interview experience was disappointing. After the first round, there was no update for nearly 2 weeks, despite multiple follow-ups. Eventually, two more interviews were scheduled back-to-back with very little notice or clarity. And once those were completed, again radio silence! They reached out to me about 3 weeks later to speak about the offer, but I declined since by then I had already joined another org. The entire process felt prolonged and unorganized. While the interviewers themselves were great, the lack of communication and professionalism from the recruitment team really diminished the overall experience. I hope EPAM takes this as constructive feedback and improves their candidate handling process in the future.
