I was offered a job with a big school that then went sour, TEFL One had me in a skype interview within days of applying and sending visa applications within weeks. Couldn't have been better.
As for Shane, I was met at the airport and everything from that point was made really simple. Handed a phone on arrival, handed detailed maps to my apartment, put on the train by Shane staff, everything was easy. Training was fun and the Shane staff are all friendly and helpful.
The work is good too, it's difficult to say as it will vary slightly from school to school (and you'll be in a different school almost every day) but generally the students are great, the counsellors are helpful and the schools are easy to find from the train stations.
The hours are slightly unsociable, most nights you won't finish until maybe 8 or 9 but the holidays (considerably more generous than just about every other language school here) more than make up for that. 3 weeks at Christmas? As a former Irish catholic with a penchant for Christmas, that was a game changer.
Overall I'd recommend Shane and would DEFINITELY recommend Tefl One. I've had a great experience thus far.
