Yes, i was told by ESF admission office that there were 420+ applicants for year 7 this year and 300+ were invited for written test. All those sat for written test had interview opportunity.
I went to the ESF secondary briefing in Nov and learned that there are approximately 120 places for year 7 - which is less than what was mentioned in their email earlier (140 places) - see picture below
Sounds like there are 3 types of so called "interview":1) Group Interview by teachers at selected school.
2) Group briefing/interview at Assembly Hall at selected school.
3) Individual interview at ESF Headquarters.
