You may get some more info on... Dave's ESL Cafe,
Yes-ish. I'd add that you're most likely to find out-of-date or second-hand information, opinion, and speculation.
Nevertheless it's still worth reading, though it's important to take things there with a very large pinch of salt.
@Maltinka, it's actually possible still to apply to the Council centrally, via their London HQ. How effective this is, I don't know It's also worth following them on LinkedIn (where they advertise) and checking out their ads (none for Poland; they don't generally need to advertise much since Warsaw has a surplus of experienced EFL Teachers) on tefl.com
Generally, once you've worked for the Council somewhere (perhaps on a short contract in a 'less-desirable' location, you've a foot in the door and have a good chance of getting more (and better) work with them. have a look at their various LinkedIn groups, especially the one for short-term contracts.
