As soon as this company learned that I have a huge teaching experience and doctorate degree they sent me a letter stated that they can't accept my candidacy at this stage. I think they are looking for unprofessionals, similar to management of the company. I also realized, that no one can learn any subject through that company, so send the a cancellation letter with the request to remove me from their list. The purpose of the company VIPKID is an income, not worries about somebody's knowledge.
