There will always be people who get hired without spending $$ on formal prep. Not the point.
To those lurking and applying…. It’s been said before but bears repeating: why would you risk a multimillion dollar career at your #1 choice by not spending a few hundred bucks on prep? You take a risk either way… Can you live with the consequences in seniority (or living in base for your career) by taking a chance by skimping and losing? Or, would you rather spend the dough, get the job comfortably, and risk saying you “wasted money on prep”?
I paid the money “back when” on prep, and felt it was worth every penny. My son will be applying in a few years and I will guarantee he will be prepared professionally, not solely by me and/or the interwebs.
