Anyone used live PM simulations to overcome technical interview fears?

Coming from marketing, technical PM interviews terrify me. Heard about practicing with veteran PMs through case simulations - does this actually help? Looking for experiences with system design or prioritization exercises. How did live feedback compare to just studying FAANG interview guides alone?

Live simulations expose gaps theoretical prep misses. Recent mentee improved from 20% to 85% scenario completion rates after 4 sessions. Critical factors: 1) Real-time pressure testing of your framework 2) Industry-specific edge cases 3) Learning to navigate ambiguous follow-ups. Prioritize facilitators from your target company size/vertical.

simulations are just expensive roleplay. better find actual pm specs online and whiteboard solutions. that time i paid for ‘expert mock interviews’? got feedback that contradicted actual amazon loops. save your cash

did a free trial sim last week - got destroyed on API questions but mentor showed me how to think aloud better. still need major prep but feels less scary now. anyone wanna practice tradeoff analyses together??
