A free library of technical-interview material from CodeSignal: practice guidance, explanations of how coding assessments are scored, interview question breakdowns and hiring-process write-ups. Useful preparation if a company has sent you a timed coding assessment.
Why I recommend it: The resource library is free to read. Bear in mind CodeSignal sells assessment software to employers, so the writing naturally presents these tests as a fair measure of skill — read it for what it tells you about how the tests work and what they reward, which is useful when one lands in your inbox.
Question banks for more than 100 technical roles — Node.js, Azure, Golang, Kubernetes, OAuth and more — each with sample answers, updated regularly. Free to read with no sign-up.
From the site: Ready-to-use technical interview questions and structured guides for developer roles and frameworks, from Remix to Magento. Updated September 2026.
Why I recommend it: Written for the people doing the interviewing, which is exactly why it is useful — you get to see the questions and the answers they are grading against.
A weekly writing community: one interesting question per week, written alongside other people anonymously, plus a chat, contests and writer interviews.
Why I recommend it: Writing well is a career skill. This is a low-pressure way to practice weekly.
A free browser-based practice aid that walks through a recruiter phone screen question by question, so you can rehearse the opening conversation most candidates wing.
Why I recommend it: The recruiter screen is the round people prepare for least and get cut in most. Run through this once out loud before your next call.
