The Minaswan::Interview

Session Format: Talk

Abstract

White-boarding is not nice. An unpaid take home project is not nice. We decided to apply the Ruby community motto "Matz is nice and so we are nice," to our enterprise technical interview process. Come learn what changes we made, how we enlisted support of other rubyists and non-rubyists alike, and how you can too.

Details

The current state of interviewing is not nice

FWIW: I (@Rondy) am not the author of the content presented here, which is an outline from Edmond Lau's book. I've just copy-pasted it from somewhere and saved as a personal gist, before it got popular on newsnews.ycombinator.com. I don't remember where exactly the original source is from and neither could find the author's name, so I cannot give him/her the proper credits.
