A short correspondence on wechat and then a 30 minute over-the-phone interview. They had said that they would normally do a second interview over the phone and perhaps even a teaching demo but told me it wasn't necessary as they were satisfied with my original interview and experience.

If you are a legal resident living in the country, you can approach the employer in person to arrange an interview. Or, you can email the company HQ to express your interest, at which point you may be contacted via Skype or other video phone-call software.
