Out of idle curiosity, how much is "well paid"? Right now I'm getting 60-70K € (It will probably end up lower because the biggest problem for specialists in Spain is that employment is highly precarious. I've worked like... 70% of the last eight months, with two or three large hiccups of one month or so. But I'm talking about a theoretical yearly-employment-with-my-current-wages. Before I leave I estimate I'll get 50-60% of the nine months I've been spinning around here). I expect the Irish to pay me around two to two and a half times as much.
Now, this is not as much about the money as it's about the perks. During the last year I've been stuck in a very small hospital in which our staff is very small (other two consultants and me), we don't get to do the more interesting stuff (or even the middling interesting stuff) and instead get a lot of chaff consultations. In my prospective employment I get a proper haemato-oncology consultation, and several junior doctors at my disposal. So it's a significative improvement. And there's also the €€€ of course, but it's not my primary consideration. It will, however, probably mean that once I start this (assuming I dont get any further paperwork problems...) I'll buy some stuff I had been wondering about for a while (eg: a 3d printer, a telescope. Possibly a new high-end laptop...)
I hope it goes alright. If I got my vibes right from the interview they intend to give me quite a few multiple myeloma patients. Which is a good thing.
