Why the last 48 hours decide it
Most interview advice carries no clock. Research the company, know your strengths, practise your answers — all true a month out, and all useless at ten at night with the call at half past nine the next morning. The two days before hold maybe four usable hours, and the order you spend them in decides how much survives into the room.
So this list is sequenced by dependency rather than importance. Finding out who is on the panel and what they work on takes a day, because it usually means messaging someone who has to reply. Rehearsing to a clock takes an evening. Testing the video link takes ten minutes and cannot honestly be done any earlier than the morning itself.
The list is fixed and identical for everyone. Nothing is generated and nothing is tailored to a job description; the ticks live in this browser's local storage, which is why the count follows you back on the same device and starts empty on another one.
