EPAM Systems Python Developer interview questions

HR Reached out to me through Linkedin. First there was a HR round in which basically she talked about company policy, work life, projects etc and took my introduction as well. Then there was 2 hour Python core technical round. He asked about how python works, OOPs concepts, decorators. Program to find the longest unique substring in a given string, database internals, database optimization, joins etc. Overall a good interview

The interview process took around 2-3 weeks, consisting of three stages: Recruiter Screening Call, Technical Interview, and Managerial Interview. All interviewers were calm, pleasant and professional throughout. The process was well-organized with clear communication between stages. The atmosphere was comfortable and conducive to meaningful discussions. A clear offer letter was delivered through a dedicated platform, which also handled the Accept/Decline decision.
