submitting right at the deadline

(common gotcha)

what happened

you wait until 11:58pm for an 11:59pm deadline. the upload stalls. the wifi drops. the submission portal crashes because 500 other people are also submitting at 11:58pm. you miss it.

why it's a gotcha

deadlines are cliffs, not slopes. one second late is the same as one week late. and submission infrastructure is least reliable when it's most loaded — right before the deadline. you're betting your entire submission on everything working perfectly at the worst possible moment.

the fix

submit a draft version early — even if it's incomplete. most platforms let you update your submission until the deadline. get something in 24 hours early, then update it as you improve it. your "insurance" submission doesn't have to be good; it just has to exist. and when you're rushing at the deadline, that's when you submit the wrong file. this is the endgame of starting too late, which is also how you end up discovering requirements last-minute.
