Pros
-You can learn a lot in IT technicalities like Business Intelligence, Data Warehousing due to initial, extensive training targeted for total newbies in subject. -great atmosphere (just like in college)
Cons
-After the initial training, you usually do very simple unambitious tasks like clicking out reports so It is just offshoring resources so that they are as cheap as possible. So -If you have experience, you will not learn anything (except from Microstrategy-specific product things of course). The work is usually boring report building. -salary is like from out of space, totally uncompetitive in Warsaw IT industry, that is why the company hires everyone that speaks English. Nothing more is needed and usually it gets nothing more back
