everyone grinds leetcode but nobody practices the actual interview conversation — so i built something for that

i've been interviewing candidates for years and noticed something weird: people spend 100+ hours on algorithm problems but walk into the room with zero structured practice on how to *talk* through a problem, explain their resume, or handle curveball questions.

like, you can solve a hard tree traversal on leetcode but then fumble when the interviewer asks "walk me through this project on your resume" or "tell me about a time you disagreed with your team." the conversation part — the pacing, the clarity, the recovery when you blank — that's what actually tanks people.

i'm vamshi, i built nxtinterview because i kept seeing this gap. it's a tool that lets you practice mock interviews with an ai that adapts to your resume and the role you're targeting. you can drill behavioral questions, do technical walkthroughs, or just practice explaining your work without sounding rehearsed. it records your answers so you can catch the "ums" and tangents you didn't realize you were doing.

started as a side project because i was tired of seeing solid engineers choke in the room. now it's live at nxtinterview.com — still early, still tweaking based on what people actually need. the idea isn't to replace real interview prep, just to fill the part most people skip: the reps on actually talking through it.

if you've ever felt like you knew the answer but couldn't land it clearly when it mattered, that's the exact thing i'm trying to solve.

would love to hear if this resonates with anyone else or if you've found other ways to practice the conversational side of interviewing.
