EPAM Systems Senior Software Engineer - Java interview questions

I recently had a four-round interview that covered fundamental Java, Spring Boot, and microservices concepts. Each round included both technical questions and a coding challenge. The questions primarily focused on Java basics, core Spring Boot features, and microservices architecture. The difficulty level was moderate, with some conceptual and practical problems to solve. Coding questions tested problem-solving skills and efficiency in writing clean, optimized code. The overall experience was decent, and the interview process was structured well, allowing a good mix of theoretical and hands-on assessments. While some questions were straightforward, others required deeper understanding and quick thinking. The rounds progressively became more challenging, evaluating not only technical knowledge but also problem-solving ability and application of concepts in real-world scenarios. Overall, it was a balanced interview process that tested both theoretical and practical aspects effectively.

There were three technical rounds, first round was of 60 minutes and second round was of 90 minutes.First one was moderate but second one was difficult. With every answer you will get a cross question. Interviewer was very arrogant.Be prepare for questions with code also, you will have to tell each and every step along with coding part..they will ask questions frome every section like database, spring boot, microservices, MySQL queries, rest apis to write and be prepared for every cross question
