Doing mock interviews with total strangers is the only thing that fixed my freezing

I could solve mediums fine alone, but the second someone was watching my brain would just white-out. Started booking mocks with random people online — awkward as hell the first few times. Turns out the thing I actually needed to practice wasn't the algorithms, it was talking while thinking. Three weeks in and I don't lock up anymore. Wish I'd started with these instead of grinding another 100 problems solo.
