Pros
Decent pay. If you are in Sales you can travel a lot and "bill" your expenses to the company. That's how my manager V De Souza lived all his life. Almost expensing $20000 a year. Use that for going to out of country vacations.
Cons
Managers don't care. They are highly ego. Very judging all the time. Very prejudiced. If you started as MTS as a fresher out of college then you gradually can succeed knowing the mess of PayPal products. If not you will fail miserably. You will be given generic training on Payments that you can find from multiple blogs and YT but after that you will be put on job which you will not be able to do successfully as you will not have any idea of the PayPal spaghetti. Managers expect you to boot lick and that's the sure way to be on the job. They constantly rewrite the PayPal and Braintree documentation and call that as initiatives or achievements.
