Aptitude online assessment , technical online assessment , technical round , human resource round some may have an additional ai interview round was generally easy , technical round they ask easy questions

I recently attended a technical interview focused mainly on Core Java concepts and basic Data Structures & Algorithms. The interview started with a short introduction about myself, projects, and my role in them. After that, the interviewer moved into technical questions. The first section was mostly Core Java. I was asked questions about OOP concepts like encapsulation, inheritance, polymorphism, and abstraction. They also asked the difference between == and .equals(), Array vs ArrayList, and basics of exception handling. Some questions were conceptual but required clear examples. Then the interview shifted to basic coding questions. I was asked to write a program to print prime numbers and explain the logic. Another question involved checking whether a number is prime using optimized logic (up to √n). I also got a Fibonacci series question and a simple array problem like finding the largest element. The interviewer focused more on logic clarity rather than complex algorithms. They asked me to explain my approach step by step and also discussed time complexity in simple terms. Overall, the interview was moderate level, mainly testing fundamentals of Java and basic problem-solving skills. If you are clear with core concepts and practice small coding problems, it is manageable.
