In reply to TheseKnivesMan: I've never heard of any such run-ins, but as Doug said those sorts of things would be more likely SNH's bailiwick.
But if you do get an interview, make sure you get the name of the organisation right - it is "Environment" not "Environmental", and it pees them off slightly when folk get it wrong.
Good luck - it is indeed a great place to work with some great people. At least it was 15 years ago when I was there!
