I also have had a very bad experience with Fly U Teach. I saw their advert on Edinburgh University's careers pages and sent them my CV. I was offered an interview for yesterday afternoon, again in Peterlee, County Durham. I initially said that I would attend, but, having thought about it a great deal, I decided to cancel my interview because I had a few qualms about the fact that their company was only established in 2007. Mr and Mrs Grebe-Spencer both called me, and both had a very vicious manner. They told me that I would be charged for non-attendance, and that they had a clause on their website saying that, if you send them your CV, you are subject to their terms and conditions of non-attendance. This is, of course, ridiculous- there is no such clause on their website and, furthermore, such charges are completely and utterly illegal. I told them that I would not be paying any such charge and contacted my careers service to make them aware of this (they have subsequently removed this company's advert from their database). I then received an angry email from Mr Grebe-Spencer, telling me, amongst other things, that he was "disgraced" with my "immature and unprofessional behaviour". He rattled on for quite a while, telling me that I would be subject to Fly U Teach's unattendance fees and would be billed accordingly. He also said that he would inform other teach abroad companies of this, saying that they "keep each other informed of bad applicants". He then ended the email by stating "I do believe you may be serving me in Macdonalds sometime soon."
It is unfortunate that we both came across this company, but I hope that you will not let this experience put you off. I am counting it as a very close call- if this is how they treat their applicants, how do they treat the teachers that they send out to Malaysia? I hate to think!
