Pros
You have lots of opportunities to influence in projects. You'll be able to understand Fintech domain. And if you interested you can learn about other projects also .. depending on your capacity, most probably you will work on a single stream. You will have lots of freedom on selecting technologies for your project.. something that you won't be getting anywhere else .
Cons
Lots of internal politics will ruin your work. No respect for employee's work life balance, they think they can call you on what ever the time they want ..middle of night or in weekends ..even some employees were asked to come to the office when they are enjoying a vacation. Have to stay in a single position for a long time to be get promoted. Most of the times they will ignore the experience you gained outside of epic. Assigning people to projects is not smooth at all.
