I think that you are right, it is great that companies are getting interview reviews on the monthly thread, especially companies that treat candidates poorly. HN is still a relatively small community, so we must all use justifiable words and beware of cognitive biases. For example, I interviewed with the company we are replying to here, and I thought that I was treated fairly. They even looked into bending a hiring policy for me.

Providing feedback is most certainly not "unfairly ganging up" . Common courtesy is just that - a common widely accepted norm. It's pretty much the antithesis of a personal "cognitive bias."
