9 years experience Java, AWS Interview
Topics: JVM, SOLID, JMM, Spring Boot, Kafka, K8s, Architectural and LLD questions.
1 coding round, 2 Technical rounds and a client round
In coding round easy difficulty leetcode question and a stream API question were asked.
1st technical round was good and mostly focused on my resume and work experience, along with System Design and SOLID principles.
2nd technical round mostly tried to question on theoretical knowledge along with a medium difficulty leetcode question. No discussion on project experience and behavioral question, which was disappointing.
Till the interview was getting cleared, I was getting calls from TA. After my last round, there is no update from TA team.
Interview questions [2]
Question 1

If you have another interview lined up on the same day so please avoid epam interview as it will take your 4 rounds of 1.30 hrs each and in last 4th round they will reject you as not technical fit... so better attend 4-5 another interviews instead of wasting time with EPAM...
