They can’t see what you submitted. They will have to answer a few questions about you (whether this person is involved in investment decision making process, etc).
Then they will have to write a short summary about what you do at work that qualifies you to get the charter.
3 short questions, and a few lines about your work. I was also afraid a bit, because I had to reach out to high level executives, but they filled in my reference within 1 day. If they worked with you, and knew you it’s really not a big effort.
