The interviewer will find your gaps in 45 minutes. Gapmap finds them first: a short conversation draws your personal map of topics, a 15-minute diagnostic measures your real level on each, and you close the gaps with study notes and mock interviews - in text or voice - graded like the real thing. 200+ topics at senior depth are free and open, no signup.
Greenhouse
Gapmap.devGreenhouse is recommended for small to large enterprises that prioritize a collaborative hiring process and need a reliable ATS to manage their recruitment pipeline effectively.

Gapmap.dev's answer:
Individual developers preparing for interviews - Gapmap is a personal tool, not a company subscription
Gapmap.dev's answer:
Most interview prep starts with practice. Gapmap starts with measurement: a short conversation about your goal draws a personal map of topics, and a 15-minute adaptive diagnostic scores your actual level on each one - so you only study what's actually weak. A topic counts as closed when you've explained it out loud to an AI interviewer that asks follow-up questions and grades your reasoning against per-question rubrics - not when you tick a checkbox.
Gapmap.dev's answer:
Mock-interview platforms and question banks answer "how do I practice?" but leave "what exactly should I practice?" to you. Gapmap answers that question first and keeps re-answering it: the map re-prioritizes after every graded answer. The entire study library - 200+ topics written to senior depth - is free with no signup; you pay only for measurement and mock interviews.
Gapmap.dev's answer:
Mid-level and senior software engineers preparing for technical interviews - frontend, backend, DevOps, system design - who have limited prep time and need to spend it on real gaps, not on rereading everything. It also fits engineers returning to the job market after years at one company who no longer know where they stand.
Gapmap.dev's answer:
Gapmap grew out of our own interview prep. The standard routine - reread everything, grind questions, hope - wastes most of its time on topics you already know. The tool we wanted didn't exist: something that would honestly tell you what you don't know, then check that you can actually explain it out loud. So we built the grading engine first, and the map grew around it.
Gapmap.dev's answer:
Next.js (App Router), TypeScript, Tailwind CSS, PostgreSQL (Supabase), Drizzle ORM, deployed on Vercel. The grading, interview and voice layer runs on Anthropic's Claude models.

I applied a ton on LinkedIn and reached out to recruiters through there. greenhouse.io is also a good one. Otherwise, Google is your best friend, and I'd hand pick positions that make you apply directly on the company website rather than 3rd party. Source: almost 4 years ago
It's insane how shit some of these application forms are. Why can't every company have something like greenhouse.io so I don't have to make a fucking account to send you my resume and then fill out a bunch of the same info anyway. Source: almost 4 years ago
Many jobs use services like greenhouse.io to post their jobs, and each job posting has an application form right on the listing. I'm applying to several companies where I'd be happy in several different positions (e.g. SWE on team X, SWE on team Y, SWE on team Z). Should I be filling out each form separately? Should I fill out just one but indicate that I'm open to other roles? Should I be trying to track down a... Source: about 4 years ago
I'd say I am not anti social, and I do get along well with people. No problem working in a team or by myself. I definitely get what you're saying though about looking like another It guy, but I just don't know what to edit. I wonder if my resume even makes it to a real person and isn't just being thrown out. I've noticed 99% of the jobs I apply for all use the same greenhouse.io format, and I never ever hear back... Source: about 5 years ago
