I was in Hangzhou a while back, and interviewed with the Hangzhou Helen company.

The contract I was offered did not in any way match what was advertised on their website. The contract I was shown did not even offer a salary or travel bonus for the Winter or Summer holidays.

I was not allowed to call or email any current foreign teachers, and the apartment they put me in for two nights was rat and roach infested and the bedding was unwashed and smelled of sweat and body odor.

No one ever asked me about any of my credentials or experience. It really did not seem to matter if I was qualified, they just seemed to want to sign anyone.

I did meet one of their current teachers in the lobby, and she told me that she had to pay for all of her own transportation and the medical check for her visa inside China, After almost 3 months she is still waiting to be reimbursed for her expenses and to be sent to Hong Kong to have her tourist visa changed to a work visa.

The impression that I got is that they offer you anything to get you in the door, and then do not follow up on their offers.
Fortunately I am in China already.

I would hate to travel half-way around the world to be offered a contract that does not even come close to what is advertised on their website.

This scammy, scummy organization goes by many different names. Be careful
