Fresh off an interview venting

Just got off an interview with a VP at a place I was really excited to be well into the process with (2nd to last round).

while it wasn't the final presentation/mock call, it did require a good level of prep in that I was told to study their top rep's demo. cool. did as asked.

I over-prepared, I'm all ready, and then ~8min in VP tells me I lack the experience the other canidates have.  Didn't test me on the platform, just a few basic questions until he let me know I won't be proceeding.

Bummed but also appreciate he was straightforward.  I asked why have I come this far, then? 

-I do see lots of their reps have been AEs for 2x as long as me.. taking comfort in that  i guess

anyone have a similar experience? My hopes  were
