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.
Element.io Gapmap.devElement.io is highly recommended for privacy-conscious users, open-source enthusiasts, tech-savvy individuals, organizations seeking secure internal communication channels, and communities needing decentralized and customizable messaging solutions.

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 love how Matrix or its most popular client Element do not even get a mention. Source: about 3 years ago
The title undersells the change a bit in my opinion. By default, mastodon now encourages new users to sign-up on https://mastodon.social which has caused a bit of a kerfuffle in the fediverse. Personally, I'm largely ambivalent to the change; I understand the reasoning, and it's what https://element.io has been doing for https://matrix.org since the beginning. It is more than a bit of a sea-change though given the... - Source: Hacker News / about 3 years ago
We currently have the Matrix protocol, with client applications such as Element supporting it. We also have XMPP as another option. Generally more modern than IRC, these platforms are primarily developed as FOSS software. This makes it less likely for developers to impact their users negatively. However, despite these advantages, these platforms lack the refined user experience (addictiveness and stickiness) that... Source: about 3 years ago

Your best bet is probably matrix, the most user friendly client iirc is element. Source: about 3 years ago
