I have an interview at ICO on March 9th. I though I read somewhere that when you interview they make you write another essay. Is this true or is it just a rumor?
Its very simple and you should be able to answer it with no problems. Just practice for regular interview questions and you should be fine. I think they just want to see that you wrote the essay submitted onto OptomCAS, too - as in you can make complete sentences with proper grammar.
