I had the unfortunate opportunity as an Accenture consultant to work on the Hertz redesign. It was a shit show and hands down the worst project I've ever been on. I left Accenture but not sure how much I'm allowed to talk about it.
Needless to say, leadership across ALL disciplines (mobile, front-end, backend, etc) was a fucking joke and they didn't listen to the red flags we brought up in literal sprint 1.
Sorry to hear about your Hertz experience.
