Application
I applied through college or university. I interviewed at HCLTech (Chennai)
Interview
The interview was pretty easy. It was more about the projects, hackathons and courses in the resume and they were looking for people with experience in dot net . It was an on-campus drive.
The interview process includes a simple resume screening, basic technical questions, scenario-based problem solving, communication assessment, and a friendly HR discussion to evaluate attitude, teamwork, and willingness to learn skills.
I applied through college or university. I interviewed at HCLTech (Nueva Delhi) in Jan 2026
Interview
The interview process was conducted in the form of a hackathon-based evaluation, designed to test both technical skills and real-world problem-solving ability.
Problem Statement: Candidates were given a real-world problem to solve within a fixed time.
End-to-End Execution: The task involved understanding the problem, data preprocessing, feature engineering, model selection, training, and evaluation.
Hands-on ML Focus: Emphasis was on practical machine learning skills rather than theoretical questions.
Code & Approach Review: Interviewers evaluated code quality, logic, choice of algorithms, and overall approach.
Explanation & Justification: Candidates were asked to explain their decisions, assumptions, and results.
Outcome-Oriented: Performance was judged on correctness, clarity, efficiency, and the ability to deliver a working solution under time constraints.
Overall, the hackathon acted as a practical interview, assessing problem-solving, ML fundamentals, and execution skills in a real development scenario.
