Bring Stock Pitch to Interview

I sent in for all my applications a written report on a stock and I sent in the full excel model I built for it.  Weirdly, landed a ton of interviews doing this.  However, I was absolutely grilled on it in every interview.  I was able to back up the research I did so I didn't fall flat on my face.  I was actually told in an interview it was the only reason they interviewed me.  However, I would make it well aware to them you know there is a huge difference between a college kid doing valuations vs a professional level Investment Banker if you chose to do it.  The worst thing you can do is act like a complete know it all.  Would also love to see people who have been in the industry answer this because Im starting work out of school officially at the end of summer so I don't know from the other side yet.
