Turned my rejection emails into a spreadsheet with the actual feedback line pulled out and patterns showed up fast
Most rejections are boilerplate but a few have one real sentence buried in them if a human wrote it. Started copying just that sentence into a spreadsheet instead of archiving the email and moving on. Eleven rows in, the same phrase showed up three times in different words — something about my system design answers staying too abstract. Fixed the actual thing instead of guessing at it.
