Unfortunately, the English speaking jobs pay next to nothing from the postings I have seen.
The ones advertised do. The good jobs pay much, much better, but they simply aren't advertised most of the time.
Those are not expats, those are immigrants working as English teachers.
Someone, please tell the insufferable twats in Kraków that they aren't expats.
Anyway, there are plenty of other jobs.
I'd especially be interested in people's experiences in sales, management, marketing, pharma, etc.
Sales - easy to get if you know what you're doing. Companies are pretty much open to anyone that is willing to build a market for them, especially in the UK or Ireland. I spotted one post a while ago that offered a starting salary of 10k + commission for the right candidate.
Management - always doable if you have the right skills, though the days of people being hired in good positions just because they're a foreigner with an MBA are over.
Marketing - plenty of people work in this, myself included. I've taken a step back this year, but I've worked with quite a few clients on freelance marketing projects as well as doing it at work.
Pharma - likewise, there are jobs for people that are actually qualified.
