An interview code submission that wasn’t even submitted changed our process
In a previous role, I was an engineering manager for a well-known company for a particular tech stack. One way we sorted through all the applications was requiring coding tests for potential candidates.

Dev build 3063 is out now, with a few small improvements. There is now an equivalent to the OSX command line tool on windows: subl.exe.
