The Orbis School interview questions

First round was with principal, this was followed by a demo of lesson, third round was with the director of the school. All three rounds went well but they were highly unprofessional. After clearing 3rd round I wasn't informed for 2 weeks if I have cleared it. I wrote them a mail asking for the status and they replied 1 week later that i was selected. Since it had been almost a month I had already accepted the offer elsewhere hence declined.
