If you have 73NG Command experience Bob it will most likely be quite straightforward on the tech stuff, limitations, personal experience stuff etc.
I think for the experienced D/E guys its more about convincing them you will fit in, keep your head down and are able to fully adopt the company SOP's. (even recently some DE guys have found the latter aspect quite challenging)
Ryanair are just looking for guys to turn up, do a good job, on time, save a bit of fuel then take their money and go home. If that basic relationship suits you all should be well but if you are looking for Smoked Salmon, Vintage Malt, red carpets and a big pat on the back, then don't bother attending. HTH!
