Summary Log:

IBM conducted an on-campus recruitment drive in 2024 with an online assessment, technical interview, and HR round. The process evaluated candidates' aptitude, technical knowledge, problem-solving skills, and managerial fit.

Online Assessment (OA) Format:

15 MCQs (2 from Aptitude, majority from Operating System (Easy-Medium), 3-4 from Linux commands and concepts) and 2 coding questions: 1) Convert IPv4 address to IPv6 address, 2) Find the length of the last word in a string with trailing non-characters and multiple spaces.

Reported Round Breakdown:

• Online AssessmentMore Online Assessment questions

Online assessment consisting of 15 MCQs and 2 coding questions. MCQs focused on aptitude, operating systems, and Linux commands. Coding questions involved IPv4 to IPv6 conversion and finding the length of the last word in a string.

Questions Logged:
