Big brand name and big pay package if you are an IITian. If you are good at algorithms and are willing to clear algorithm tests every year, then your position is secure in the company.

1. Incompetent work. It's an R&D center, and they are reluctant to bring expertise into their project. Their only requirement is to first grab any project from HQ somehow and then complete it somehow.

2. They have algorithm tests to clear. Every employee has to clear till a professional level of test to remain in the company.

This way, you will not have any technology experts (like frontend, database, Hadoop) or technical architects. You will only remain with the group of people who have cleared the algorithm test.
