asked a stranger from this forum to trade mock interviews instead of paying $150 a session

Been grinding leetcode for two months and kept seeing mock interview services charging like $150 an hour, which just isn't happening on my budget right now. So I posted in the intros channel here asking if anyone wanted to trade sessions, 45 minutes each way, and got three replies within a day. First swap was rough, my partner froze on a graph question and I probably rambled through my own answer, but we both walked away with notes we'd never have caught alone. Cost me nothing but time and a little pride. If you're broke and prepping, just ask, people are way more willing than you'd think.
