Behavioral Paired With Design: The Bar-Raiser Pattern
A 4-question reconstruction of a bar-raiser loop where every behavioral prompt opened the door for a design follow-up. Each question pairs the story I told with the sketch I had to draw 20 seconds later.

A bar-raiser opened with: "Tell me about a time you pushed back on a technical decision you disagreed with." After my answer, they pivoted: "Now sketch the rate-limiter you would have built instead." I had 20 seconds to switch gears. Show the data structure I drew and explain why the bar-raiser pattern pairs them this way.
From the loop notes
I drew a sliding window counter on the whiteboard:
allow('user-42'); // t=0: window [0,60), count 1, returns true
allow('user-42'); // x99 over the next 50s: count climbs to 100, still returns true
allow('user-42'); // t=51s: count 101 in current 60s window, returns false3 more questions and all solutions are locked.
