There are some very good points here.

EF in Changsha pays 5000 to 9000 a month = that’s below average for training schools.
It’s even below average for public schools, public school that only require actual class hours and not office hours.

Before you hit back with "EF provides trainning...
" that’s all bull. If you are a real teachers then you don't require a pay cut because the job includes training.

Half of the training given at TCs is bullshit, if you have already done a TEFL course or have experience, that training is not something that you need.

When I worked at a TC, we just saw these training sessions as an excuse to sit down and do f**k all. Even the 'trainer' admitted it was a load of shit and did not take it seriously, he just did because he had mysteriously been picked out for a future promotion. They were really just reading from a CELTA student book (not even the materials intended for the trainer) that had been left behind by a former teacher most of the time.

Also, it could be argued that if you are actually qualified to teach... Very little training will be needed!

Before you come back with class size
Give me a large public school class where students have to behave and pay attention or their grades suffer rather than a load of private paying students who are over worked and tired at the end of the evening.

Not to mention that sales guys will often ignore those class size limits and give you too many students anyway. The paying students then feel pissed off because they aren't getting enough direct personal attention and then blame you, not the sales guys.

Half of the customers are also the spoilt brats of rich parents, who have been sent there of their own will, due to failing to perform at school. No surprise that half of them have no discipline whilst in class at the TC either.

Before you come back with class support
All decent schools worth their salt will support their staff, if they have to boast about this basic requirement then you have very little to offer.

'Class support' at a lot of TCs and agents simply equates to spying and interference. In my opinion, good support means having approachable managers who you can sit down and talk with, when there is a problem. Although not everything is perfect at my university, there is the occasional error etc, I know that I can call my superior or go to their office to have a chat, request extra advice, materials etc as and when needed.

I always see EF getting bashed on this site and many other sites so last summer I accept a few interviews with some of their branches just to make up my own mind about EF. I mean there's no smoke without fire and we know many expats like to boast so I figured the best way to find out for sure about EF was to do a little research.

I can honestly say the interviews where shocking. Between the non natives interviewing me that could hardly speak English and the D.O.Ss that told me they don't release salary till the second round interviews and the Chinese staff that just lied to me about hours, I was shocked. I should point out that I was offered every job and all the schools sent contracts for me to sign. I of course did not sign and made my excuses however I did record the interviews to play back and watch.

My short experiences with may different EF schools gave me enough of an insight to see that they are not creditable schools and I would not recommend ANY foreigner to work for them.

True, when you have an interview, it is a two way process... Too many people believe that it is a case of you proving that you are the right person for the job. I have learnt in recent years, that you should use the interview as opportunity to find out if that company is right for you, if they are trustworthy, etc... Remember that you are not obliged to instantly accept an offer, you can reject job offers or negotiate for better terms!
