Communication is a two way street, I wouldn't immediately blame one party, although you would think they would mention the process from the outset.

'unreasonably arduous'- how would you define that. Really a few phone convos, a take home assignment and showing up for interview is unreasonably arduous for a diverse candidate?

This actually shows to me that the company is not willing to hire someone diverse without properly vetting them. Good for them.

It was an observation. I can't help if they were insulted.
