what's in an experienced designer's portfolio? School me??

How you think, how you work and what you can do is more important that what you have done. People should be hiring you for you can do for them in the future, not necessarily what you’ve done in the past.

If you can show this though “new” process, sketches, examples and a combination of go to market stuff you’ve done you should be OK.

PS. Always have a backup.
