The company has a two step interview process. The first is a general interview where you talk with a HR manager, head teacher and branch manager. Typical questions about experience, motivations for applying. The managers I interviewed with were extremely friendly and th einterview was very relaxed.
The second Interview I was given some english grammar and was asked to prepare how I would explain/teach this to students. This was in front of HR and 3 other branch managers but again quite relaxed and friendly.
