This is two times that I apply for a job as an English teacher for 2 hours a week. Each time, a person calls me to set up a telephone appointment (appointment set by language connection, and not by myself), then, the next day, a new call to say that the position has been filled !!! However, my request was made immediately after receipt of the language connection offer !!!! The positions seem quickly filled, even even before the offer appears ... In addition, I am told that I will be contacted when a new request ..... I was not contacted for the second offer ... Let me doubt the seriousness of the business. cordially
