Pros
Much freedom in approach to customers and to structure the own work. Working from often home possible if ok with Manager, even if no official home office worker. Good if you do your numbers. Often easy to approach customers, cause most of IT staff know Oracle very well. Whole areas at many customers are dedicatedly working with Oracle software.
Cons
Lots of reports on numbers details doing for management. Often ad-hoc requests for detailed figures etc by manager, cause he needs to report this to his manager very fast. Salary: For most people who started at Oracle Germany in telesales, the salary does not appropriately rise even after they moved on to more senior field sales positions. This is why many such staff stay in Oracle field sales for around 1-3 years and then move to other companies to realize strong salary growth. Some come later back to Oracle and then even get additional salary growth on top of that. So Oracle would be wise to pay appropriate salaries to such staff, to avoid losing staff who know all about Oracle and are in a age where they are wiling to really work hard in order to make a career.
