Very brief, mostly how you are with children and education qualifications. How have you handled difficult situations before. It was 1 on 1 interview, usually in a cafe to make you feel comfortable. Previous work with Kumon worksheets preferable

They do an online interview over Zoom once, where they ask you general interview prep questions and other questions about your resume. They then invite you for an in-person interview and make you take a small math test alongside it. The whole process takes months. They sent me an email saying they liked me. Then 3 months later, when I had already gave up hope, they emailed me asking if I was still open to working there since they were still deciding. Never got another email since.
