Questions posées lors d’un entretien d’embauche pour AVP-Java Developer chez EPAM Systems

It was a face to face interview in Yerwada, Pune office. They took a test of 3 questions and asked to solve them. 1. Binary search tree for integers - calculate the depth and largest no. 2. Remove chars and specials chars from string and print it to integers. 3. Some array program with negative index. I could solve Q2 only correctly and they call me for interview. Interviewer asked me about my projects and he started deep dive into Kafka, because I was not that prepared got stuck. And he gave a negative feedback for me. No questions on core java, springboot were asked in the interview.
