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.

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.

The Home screen will be the entry-point of the application, where the active conversations can be seen by the user. It is also the place where SignalApp can be configured, when tapping on the User avatar on the top left of the application, a Drawer menu should open. This menu is not displayed on the screenshot, then, only an empty one will be created. - Source: dev.to / about 1 month ago
Signal's requirement for phone numbers has allowed it to surge in popularity by allowing it to take advantage of people's already established contacts. They do this in a privacy respecting way[1]. Simultaneously, Signal is trying to raise the cost of accounts by requiring phone numbers. Although spammers can get mass amounts of phone numbers, it will at least raise the cost. Email 0 cents, phone # 10 centsโthere... - Source: Hacker News / 2 months ago

This is the Moxie that created Signal.[0] I'm pointing this out because people are acting like he's a bit naive. But Moxie has built a very successful company, without the need for VCs, and the tech is used by many big tech companies. Several use the signal protocol. It's a successful nonprofit building open source software. If your focus is to make large amounts of money, maybe his isn't the best advice. But if... - Source: Hacker News / about 1 year ago
