The interview process consisted of four rounds.

Round 1: Online Test This test included sections on Aptitude, Logical reasoning, Verbal ability (which was quite easy), and Technical topics such as Flowcharts, DBMS, Algorithms, OS, and Data Structures.

Round 2: First Interview This round began with a discussion of projects listed on the resume. Following that, questions on core Java concepts were posed. I was then asked to write a program to determine if a string is a palindrome. The interviewer concluded this session with a mathematical puzzle.

Round 3: Second Interview This interview was quite challenging, and the interviewer was not particularly friendly. Questions focused on DBMS, specifically ER diagrams and SQL queries. I was asked to write a program to compute the Least Common Multiple (LCM) of a list of integers. I proposed a brute-force solution, but it was not satisfactory. The interviewer also asked questions on linked lists and Binary Search Trees (BSTs). While I had answered almost all questions up to this point (except for optimizing the LCM program), I was then asked a question from the pre-placement talk given that morning. I was unable to answer it, which was likely the reason for my rejection.

Round 4: (Details for this round were not provided in the original text.)

Is 22499 a prime number?
