The Big TEFL Schools

I'm looking for a school to work for in Prague and there are so many, but who are the best ones? And, how do you rate them as good? There are some big name people here like Caledonian but I was truly shocked at they way they run things. Firslty, they were very disorganised and lost my details after applying to them. Their sense of politeness did not even exist and the staff were somewhat rude. I guess customer service here is not like in the States, but the reception staff could not even speak proper or decent English, and as for being nice....well, that was rather like rudeness. I went to Caledonian for an interview and just crudely told to go up to some room and wait. I waited and waited....and after 20 minutes, a man appears. I was interviewed by a director called Tomas Vokac who was over 20 minutes late. Then he rambles on about some demo class that was never even told to me. Anyway, he tells me it's great and that I should expect a contract within 1 week. But, this never happens and I am forced to call the school and speak to the rude reception staff. They knew nothing about the interview and the notes from that man. How disorganised and pathetic is that? Well, it just goes to show that maybe size is not everything and just those big name schools are not worth it. Caledonian merged with Tutor school recently and they are very proud of their big size, but are they really good for teachers? A friend told me how he felt that Caledonian were even racist too and they have a certain tendency to favour white teachers rather than colored ones. What are your opinions on the big schools in Prague? Can you recommend any good ones?
