Recording myself answering behavioral questions on my phone was more useful and more cringe than any mock interview I've done

Practiced out loud for weeks and felt fine about it until I actually watched a recording back. Filler words I had no idea I used constantly, a habit of trailing off mid-sentence when I lost confidence in the answer, way more 'um so basically' than I'd have guessed. Painful to watch the first time. Did it once a week for a month, watched myself less irritating each time. Cheaper than another round of paid mocks and honestly more specific feedback than most humans give you.
