GitHub Rails Developer interview questions

Based on the Resume and Coverletter submitted, I was shortlisted for the Interview. Hence, I started contributing to their open-sourced project (classroom). Merely 2 hours before the scheduled interview, the HR representative mails me that they've found a match for the role and hence the position is closed now. This is pathetic. But wait, it doesn't end here. GitHub was atleast gracious enough to reward my contributions and correct this pathetic experience with some Goodies. Yes, they really are gracious enough to offer a free Hoodie and Tee. Though, I'm yet to receive them.
