I applied online. The process took 2 weeks. I interviewed at IBM (Hyderābād) in Mar 2024
Interview
The first stage of the selection process was an online coding assessment. The assessment included questions on data structures, algorithms, and problem-solving. It also tested my coding proficiency in programming languages like Java and C++. The test was time-bound, and I had to showcase my ability to write clean and efficient code under pressure.

Question 1
Chocolate Problem
Given an array/list of integer numbers 'CHOCOLATES' of size 'N', where each value of the array/list represents the number of chocolates in the packet. There are ‘M’ number of students and the task is to distribute the chocolate to their students. Distribute chocolate in such a way that:
1. Each student gets at least one packet of chocolate.
2. The difference between the maximum number of chocolate in a packet and the minimum number of chocolate in a packet given to the students is minimum.
Applied through the company portal, completed an online coding assessment, followed by a technical interview covering data structures, algorithms, OOP concepts, and project experience. Concluded with an HR discussion about the role, career goals, availability, and compensation expectations.
## IBM Interview Process
The process began with initial resume shortlisting, followed by competitive **DSA and coding rounds** to test core technical concepts. After clearing those, I cleared two comprehensive interviews with the **Hiring Manager/Tech Expert** and **HR**.
Describe the interview process: The process consisted of three rounds: an initial online assessment focusing on data structures and algorithms, followed by two technical video interviews. The technical rounds were intensive, covering system design, live coding, and deep-dive questions into previous project experience and database optimization.
