Pros
In the past, working for eBay was good way to improve your CV. I also found it quite fun to be working for a well recognised brand. When I started in 2002, eBay was an exciting place to work. Everyone in the team could share ideas and had a genuine feeling to be part of the success story. That all changed when the struggle for power started. So many good projects and ideas got killed as they came from the "wrong" country, product group or team. Smaller countries like FR, BE or NL simply could not do what they knew to be best. So many people got frustrated or depressed and left or got kicked out.
Cons
The company could not handle change. The problems seem to have started when the company was growing too fast. Carreer development was at first not an issue and then it became unpredictable. I have seen the dice roll both ways for me.
