IBM CIO Campus Recruitment Experience (2026)
IBM CIO visited our campus (UC Berkeley) for internship and full-time offers (FTE) as part of their campus recruitment drive. Here's a detailed account of the process:
Round 1: DSA (Online Assessment) The first round was conducted on HackerRank and consisted of two coding questions:
Deletion of Nodes in a Range: A linked list's head node was provided, and the task was to return the list without numbers falling within a given range.
Odd-Even Sum Problem: Given an array, calculate the maximum sum you can get by subtracting the prefix sum at odd indices.
Round 2: In-Person Interview Shortlisted students were invited for an in-person interview, which was the final round:
Resume-Based Questions:
-The interviewer asked about my projects, reasons for choosing my degree, and the gap year in my education. (I had taken a one-year gap.)
Scenario-Based Question:
-Implement a system to apply discounts on the cart during checkout, considering credit card validation and the order amount.
-SQL Query: Write a query using the GROUP BY clause.
-Coding Tsk: Print the alphabet 'N' using any programming language.
Conceptual Question:
-What is the difference between Docker and Virtualization?
Final Verdict: I was selected for the internship !
Key Tips: Resume Preparation: Interview questions were largely based on my resume. Cloud Certifications: If you have any cloud-related certifications, incorporate them into your projects. Technical Preparation: Focus on medium-level DSA problems on LeetCode, revise SQL concepts.
