Is it wrong to ask why if you don't get an interview/superday?

I did not get a first round interview that I 100% thought I would for SA. I go to a target for the firm, had networked with the guy in charge of recruiting, 3.9 GPA, prior experience, etc.

Did not even get a first round. This is after the guy specifically explained the complete recruiting process and when the superday would take place when we talked and meeting in person at an event.

Would it be wrong to ask if I made a mistake/what I should improve? Still can't believe I didn't get a first round.
