Question 1
prior experience and basic questions related to my profile
The process was an in-person, full-day interview at the HCL office. It began with a hackathon as a group of 5 people, where we designed and developed a complete end-to-end architecture for a delivery application. This was followed by a one-on-one technical interview. A few days later, the HR department reached out and offered me the job.
