If I had the money to fight the lawsuit, I'd be right there.

Also, I formally let them know I disagreed with the psychometric testing.

Double also... I used to apologise to new hires for the psychometric testing, and tell them "this is not how the real-world works, this is a micro-community"

Fight the smart battles - and know the parameters of your influence ie don't be labelled as public enemy no.1 by dis-agreeing visibly.

Personally i think hr's role in selectin should simply be one of co-ordination and documentation, nothing more. Selection should be done by the team that needs them, with even the managers of the team playing a supporting role ie team decides not even the project manager. That requires a strong CTO/CIO type person and supporting CEO etc.

But, more importantly, by allowing HR to label you as a dis-ruptor and someone who threatens their own influence, it will be tough for you in the long run
