Know

so i posted here a while back about my job search being rough. career switcher, bootcamp grad, 3 yoe backend. wasn't getting callbacks for weeks then started getting phone screens and... promptly bombed all of them lol the problem wasn't that i didn't know the material. when i practiced alone i could talk through system design and behavioral stuff fine. but the second someone was on the other end asking follow-up questions my brain just shut off. i'd give these rambling non-answers and then immediately know what i should've said after hanging up. every single time. what actually helped was something embarrassingly simple — i started doing mock interviews with real people. i know everyone says "just practice with a friend" but my friends are either not in tech or also junior and we'd just end up reassuring each other instead of actually pushing back on weak answers. i tried a few different things: - pramp was free which was nice but the quality was super inconsistent. sometimes i'd get matched with someone who clearly didn't read the problem, or someone way below my level so neither of us got much out of it - ended up trying meetapro where you book sessions with people who actually work at faang companies and do real interviews. not free obviously but having someone who actually interviews candidates at google tell you "that answer wouldn't pass my bar because X" is a completely different experience than practicing with another job seeker - also did a couple sessions through interviewing.io which was decent, more structured format the biggest thing i learned: my answers were too long. like way too long. in my head i was being thorough but from the interviewer side i was apparently burying the key point under 3 minutes of context nobody asked for. one mock interviewer told me "pretend you have 30 seconds, what's the one thing you want me to remember?" and that reframing changed everything. ended up getting 2 offers after about 5 weeks of doing 1-2 mocks per week on top of my regular prep. not saying mocks are magic but for me personally the gap between "i know this stuff" and "i can communicate it under pressure" was enormous and i couldn't close it alone. if you're in a similar spot where you KNOW you know the material but keep choking in actual interviews, honestly just try talking to a real person about it. even one session might show you what you can't see yourself.
