Has anyone done the MoMath High School Integrator's program?

Hi all! I can’t seem to find any info about this outside of the MoMath website. I applied to the summer version and have an interview scheduled for this week (any advice/tips would be much appreciated)—I was wondering if anyone else has done this internship in previous years? If so, how was it, around how many other high schoolers did you work with, and would you recommend?
