HackerRank was entering a competitive field of sites for programmers. Knowing we were offering something a bit different, we wanted our launch to be unexpected and fun.
I came up with the idea of hosting a live terminal shell in the browser. Users could sign up by interacting with the terminal through a few simple commands (complete with instructions for those who needed a bit more guidance). Once people signed up, the would get to work on some simple code challenges and rack up points for early access.
The site and leaderboard were a hit in the development community. Within the first week, we got 10,000 new signups for HackerRank through the terminal.
