Twitter waterflow problem and loeb (2013)

I heartily recommend this short accessible article to anyone interested in loeb:

Didn't get attention here when the story was new:

Usually the companies I've interviewed with don't like their candidates sharing the problems they failed at afterward. I wonder how Twitter feels about this one getting out?

(this wasn't posted by me)

I think the golden rule is nonsense, or a recipe to be exploited; I try to live my life by reciprocal altruism or tit-for-tat with a cooperative opener.

The point is, if twitter feels bad about candidates sharing, they should make a lot more effort to treat candidates with respect. I had a pretty terrible interview experience: I was an internal referral, and despite that, I not only had to sit on recruiter for updates, but after a full day interview they dropped all contact. I'm a big boy: if the answer is no, that's no problem, it's not a fit. But very basic courtesy would have them drop me an email after I gave them a day of my time. I'm not saying that's what happened here, but I've heard plenty of stories similar to mine.

Eh, this is a basic programming puzzle that is older than Twitter
