Round 1: Online Assessment

The first stage of the HCLTech recruitment process is the Online Assessment, conducted through a secure, AI-proctored platform. This round evaluates a candidate's numerical ability, logical reasoning, English proficiency, computer fundamentals, and coding skills. It acts as a major elimination round, and only those who meet the sectional cut-offs proceed to the technical interview.

The assessment pattern may vary depending on the role, but the question format and difficulty level remain mostly consistent across drives.
