I was a very early eBay employee in one of their non-US locations.
The company culture definitely changed between 1999-2002. By 2003 I was gone, mostly due to friction with management, somewhat to do with my immaturity in dealing with it.
In those early years, powersellers were already being actively courted, but there was still a strong recognition of the small collectable buyers and sellers.
This attitude changed as more MBA holders were brought in to run the show. Fees were constantly creeping upwards and largely irrelevant advertising was introduced. There was always a real focus on the quarterly earnings announcement and trying to hit the numbers no matter what. This introduces friction between shareholders and customers, with shareholders almost always winning because the employees all held options and obviously wanted the share price to continue to rise.
Having said all that, I had a mostly very fun three years working there. Just the last 12 months were not such a happy time.
Subsequently, I bought and sold a lot on the platform, including reasonably high value motor vehicles. I haven't bought or sold in over 12 months now.
