04 Try it yourself Interactive

Run the same interview twice

The left tab runs Two Sum through all six steps. The right tab gives the same candidate the same problem and the same knowledge, and starts them typing at minute one. Watch the six-step rail: in the second run only step 5 ever turns green — the other five are marked skipped. Use the drop-down to throw in the curveball. Nothing moves until you press Next.

Six-step run
clarify → examples → brute → optimise → code → test
The interviewer stays quiet and lets you drive.
Press Next to begin. Each press is one move in the interview.
