Pros
1. Better work life balance than the peer companies 2. Good training programs 3. You have a good chance of getting a good exposure to projects responsibilites early in career if you show commitment and ask for such roles. Thus you can learn early in your career what your peers in other companies get to learn later in life [this is also due to the fact that middle level managment in the company is usually short in supply and is groomed on the job].
Cons
1. Promotions are not competency based. Instead a key factor determing promotions is the number of years of spent in the last role. Not rewarding for exceptional performers. 2. Support systems work like govt organizations. 3. Public Sector like Hierarchy culture. 4. A very complicated salary structure - substatiatial portion of the salary is variable. 5. Not the best paymasters. 6. Internal unit transfers rare and unofficially discouraged.
