Paid for a real mock interview service after months of practicing alone and immediately saw what I couldn't see myself

Was skeptical about paying for something I assumed I could just replicate with a friend, but a stranger giving direct feedback on a recorded session hit different than a buddy being nice about it. Biggest note wasn't technical at all, it was that I trail off mid sentence whenever I'm unsure, which apparently reads as way less confident than I actually am. Never would have caught that practicing solo.
