Some advices for teachers searching for a job

In Russia: do not to be swindled!
Don't take any course that is less then 4 weeks in length. Don't take a course which doesn't offer hours of it practice teaching on real ESL students. Never consent to pay for practice teaching. You have nothing to do with a course, that stuffs 30 students into a hotel room. A course that doesn't teach comprehensive grammar for ESL students should provoke suspicions.

The courses that say don't fail anyone ever, promise that anyone can teach English, focus on money and fun (travel) as the main reason to teach ESL and, finally, make everything sound too good to be true are not reliable! Do not collaborate with them.

Send in inquiry that looks professional
The letter should be grammatically correct, have no misspelling and follow the instructions, given by the employer (such as not using attachments, for example). Other way recruiters will obviously conclude that you are not a native speaker of English or that you do not have a proper education. At the very most they would place candidates, who sent the incorrect letters, at the bottom of the hiring list.

Also, if you send in resumes that are 3-4 pages long, they may just skip them as they don't have time to read over a book about your life history. Be concise when writing letters and resumes. Try to keep everything down to a page. Try to put relevant information in your resume or letters. The same refers to the attachments - you'd better not to send them.

And they probably wouldn't respond explaining the reason for rejection, as they are too busy.

If you did it all right, you have to be patient waiting for the answer
Because of the great amount of the mail coming to the recruitment office, it's hard for the officers to answer quickly. It might take quite a long time to get back to some people. Remember applying for your University admissions: it probably took a month or more for them to even acknowledge the receipt of your application.

Or make a phone call!
A phone call is going to get you a much quicker response than a letter. You can do a two-pronged approach of e-mail and phone calls. Recruiters have a lot of inquiries and offers to choose, so it is in the teacher's best interest to be persistent (but not annoying).

Good luck!
