Donโt waste hours scheduling the same interview over and over again... Invite candidates to complete an automated video interview. Reserve your time only for the best candidates. It literally takes seconds to create one-way video interview. Once the interivew is set up you can focus on your other tasks, while the candidates can complete their video assessments in the comfort of their homes.
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.
HireFunnel Gapmap.devHireFunnel is recommended for small to medium-sized businesses and recruitment agencies that seek a scalable solution to manage high volumes of applications more effectively. It's also well-suited for teams that want to enhance their recruitment strategies with data-driven insights and those looking to reduce the time-to-hire while maintaining candidate quality.
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.
"It certainly makes it much easier to filter through the applications. I review everyone myself, then I show the interviews to the managers and other team members, so in the end we make a group decision, but without any of us sitting in on the call. "
