      Backend Developer Interview

      29 Sept 2025
      Anonymous interview candidate
      No offer
      Neutral experience
      Average interview

      Application

      I applied through a recruiter. The process took 3 weeks. I interviewed at EPAM Systems in Jan 2025

      Interview

      The interview process started with a short HR call where they asked about my background, main skills, and motivation for joining EPAM. After that, I had a technical screening with coding tasks focused on Python, algorithms, and SQL queries. The next step was a live technical interview with a senior engineer, where we discussed Python best practices, Django/Flask frameworks, working with REST APIs, and database optimization. They also asked system design questions, mostly related to microservices and scalability. The final stage was a soft-skill interview that focused on teamwork, communication, and problem-solving approaches. Overall, the process was well-structured and professional.

      Interview questions [1]

      Question 1

      How would you implement authentication and authorization in a REST API using Python? Explain the difference between multithreading and asynchronous programming in Python. How do transactions work in relational databases? How would you optimize a slow SQL query?
