Pros
Get to learn banking domain. Flexible timing allowed (at least in my project) - depends on the manager.
Cons
Oracle Financial Services Software Limited (OFSS) was formerly i-flex, which is acquired by Oracle. Flexcube is its corebanking product. AND I JOINED MAINLY BECAUSE IT IS ORACLE NOW. 1) It takes lot of time to get hang of functional and technical aspects of the product. Too vast really. Hence it take lot of time to start being productive. 2) Unreasonable customizations accepted. Why build such a huge, complex and generic product then? 3) Poor program management. Employees will bear the brunt of this. 4) Very tedious/lengthy process of doing product changes. Doing a small thing takes ages due to internal dependencies. You will learn nothing out of it. Process is constantly changing and no documentation. 5) Very poor work-life balance in an active assignment. 6) Onsites are mainly in developing countries and are poorly managed. Employees slog at onsite. 7) The work has to be within product boundaries and according to its framework. No lateral ideas required nor entertained. Hence no learning or restricted learning only. Any additional skill-set you have is totally wasted. And existing skill sets would evaporate soon. 8) Bonus is shown as part of CTC in the offer letter. And they hardly give 30% of it. 9) No hikes nor increments. Forget about promotions.
