What's the failure rate for aspiring investment bankers?

I've been on this forum for some time, and I've noticed that many post their success stories but stories of failure are rare. Because of this, I feel that it's possible that a representation bias may exist within WSO regarding how many people actually achieve their goal of getting into the field. So what's your story of failure at trying to break into Investment banking? Also, what percentage of people who apply for IB positions actually make it?


Goldman: 2% Acceptance Rate
BAML: 3% Acceptance Rate
Citigroup: 2.7% Acceptance Rate
Deutsche Bank: Unknown
JPMorgan: 2% Acceptance Rate
Morgan Stanley: 1.25% Acceptance Rate

These stats are from 2016. If anyone else has stats of other banks feel free to share, as this was all that was readily available online.
