everyone grinds leetcode but almost no one practices the actual interview conversation

i've watched friends bomb interviews not because they couldn't solve the problem, but because they couldn't explain their thought process clearly or handle a curveball question without freezing.

been thinking about this for a while. most candidates spend 40+ hours on leetcode, system design, and technical prep. but how much time do they spend actually practicing the conversation part? like, talking through their resume without rambling. answering "tell me about a time you failed" without blanking. explaining a solution out loud while someone's watching.

almost zero.

i kept seeing people who could crush a problem on their own but fell apart when they had to verbalize it under pressure. or they'd get a behavioral question and their answer would be all over the place.

so i built nxtinterview (nxtinterview.com) to fill that specific gap. it's a tool where you can run mock interviews — behavioral, technical walkthrough, resume-based questions — and actually practice the speaking part. you get feedback on clarity, pacing, filler words, all the stuff that matters when you're in the hot seat.

i'm not saying leetcode isn't important. it is. but the interview is a performance, not just a problem set. and most people don't practice performing.

full disclosure: i'm vamshi, i built this as a solo founder. not trying to pitch hard, just sharing what i noticed and what i'm working on. if this resonates, check it out. if not, no worries — just wanted to put the idea out there.

if you've ever felt like you knew your stuff but couldn't get it out right in the interview, this might help.
