You are both anecdotally and factually incorrect. Go on LinkedIn and set past company to Uber. Most engineers (and nearly 100% I personally know) are either at Netflix, Facebook or Google. These companies in fact set targeted recruitment tactics in 2017 for Uber employees. I got emails from every company imaginable when the Susan Fowler report came out.
You might be right.
But there are many people making hiring decisions who are just as naive as I am, so the Uber brand doesn't help.
