Well, I don´t see any real cons´ at DFW but let me tell you about some other points:
- Unfortunately, you need to work
- Your colleagues ask you to go for a beer after work
- DFW takes the whole company once a year for a few days to a nice hotel in Wroclaw or Zakopane for example, where you spend time with your teammates, have fun, activities, have some nice dinner, and drink again ;)
