Ask HN: Interview rejected, extra freedback after offical. Laws broken?

About 1 year ago I interviewed at company X. I was rejected, but the interviewer told one of their employees his opinion about my interview.

That employee is a friend of mine and they 'politely' (unofficially) relayed that information to me after I received the official rejection letter from the company. I was honestly offended by the 'politely turned' feedback my friend gave me, which was uncalled for and quite frankly unasked for.

The "feedback" was essentially "I don't know what I'm doing, go some where and learn how to do the job you already do on a daily basis, then interview here another time.". This was all based on a sub par 15 minute phone screen (both on my end but very very much on the interviewers end - one of those people you just wouldn't want to work for kind of interviewers).

That's besides the point, were any laws broken in this case?
