Avantages
Salary is good for experienced people. Best part is the variable component is 10% and you get the complete variable component. If you want to learn technology, there is ample amount of scope to learn here. You get good amount as conveyance and shift allowance if you work in shifts. There are additional benefits like Internet bill reimbursement, working from home, good amount of health/life insurance, for certain job levels, you get tax benefit for your car fuel and driver's salary.
Inconvénients
For some of the departments, you need to work in shifts. Some of the shifts are very pathetic. Nothing much apart from work, i.e. very less recreational activities. If you are highly experience but not/less experienced in Teradata, you will be treated almost as a fresher. You will get a horizontal growth (in terms of learning), but vertical (in terms of roles) growth is limited.
