It doesn't matter if they know what they are or not. You can go in and tell them, and what this shows is that most mentors can't wait 15 mins to see if they can progress or not. If you can't be patient for that long and they (sprouts) are still trying with you and are willing to learn. If they aren't they will leave and you can follow suit. The whole point of this post is for the mentors who abuse it.
