Interview Preparation Tips

Interview preparation tips for other job seekers - Salary: 5 LPA; Bond: 1.6 years. My experience was quite poor. Initially, we were required to report at 9 AM, and our workday extended until 10:30 PM. We were not provided with any dinner or food after 6 PM, only receiving coffee, and we were prohibited from going outside to get food. Subsequently, we were called for an interview on a different day, but despite passing the HR round, I was ultimately rejected. Out of the initial group, only 20 candidates reached the technical interviews, and only 2 or 3 were extended offers on the same day.
