Well, it's pretty common to have 10 x 1 year of experience. Lots of jobs require the repetition of a relatively shallow set of skills.

When I started my current job I remember the announcement said something like 15 years experience and I thought "I've been doing lots of things for a long time, but I don't feel like I have 15 years experience in any of them" at least no the same way someone in a more stable domain might...
