I applied about a month before I heard back from them (I'd actually forgotten I'd applied). They wanted me to for the test two days after the email which was impossible. They then said they weren't able to reschedule a test, then lo and behold, the next day they suddenly decided they could reschedule the test.
You have a 1.5-hour written test spilt into five parts. This was handwritten, not on a computer. You have to use such basic English, no idioms, metaphors etc (it sounds really dull when you've written it), as most of the viewers are not native speakers.
