did three paid mock interviews and the only useful one was the free peer swap with a stranger from a discord server

Paid for feedback and got generic notes I could've gotten from a rubric. The peer swap partner, who was just as nervous as me, caught that I kept saying 'does that make sense' every thirty seconds in a way neither paid service mentioned. Sometimes the person who's bad at interviewing in the same way you are notices your tics better than someone who's good at it.
