Why I recommend it: Bring a range, not a single number, and anchor it to this data.

Why I recommend it: Write six stories. They will cover about 80% of the questions you get.
A free resource library from Harvard Law School's Program on Negotiation, with articles and guides on negotiation strategy, conflict resolution, and dealmaking.

A mentorship platform that matches you with a mentor working in your field — design, product, engineering, marketing and more. Signing up and your first session are free.
Why I recommend it: Free to join and the first session is free; ADPList also promotes paid plans and some mentors charge, so check the mentor page before booking. Free-tier value: browse mentors, book open calendar slots, ask for a portfolio or interview review.

From the site: Upload your CV — AINA builds your profile, matches you with relevant jobs and keeps your applications in one place. A career coach preps you for interviews.
Why I recommend it: Free to start on the job-seeker side; the paid plans are aimed at the companies doing the hiring. Remember your CV and video go into a recruiting platform, so treat it as sharing your details with employers, not a private notebook.

3-minute AI-assisted assessment based on Lou Adler's BEST personality test to help interviewers recognize which candidates they systematically misjudge.
From the site: Specialized AI assistants and templates for performance-based hiring workflows
Why I recommend it: Helpful for understanding what interviewers actually look for—and the biases that shape first impressions. Use it to prepare smarter, not just harder, whether you are interviewing or being interviewed.
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.
A candidate-reported database of companies that stopped responding after interviews. You can search employers or submit an anonymous report of your own.
From the site: Ghosted after a job interview? Submit an anonymous report and see which companies candidates say stopped responding after interviews.
Why I recommend it: Being ghosted is not a reflection of your worth. Check a company here before you invest in a five-round process, and log your own experience so the next person walks in informed.

From the site: AI Career Day: practice a real interview with the Eightfold AI Interviewer and get personalized feedback in minutes. Free. No resume. 18+.
Why I recommend it: Use it as a low-stakes rehearsal. The feedback will not replace a human coach, but hearing yourself answer out loud once removes most of the nerves from the real conversation.

Why I recommend it: Applications open each fall and close by mid-December for the following year. The squad accountability is what makes people actually follow through.
U.S. Department of Labor-backed interview preparation guide for general audiences, covering how to prepare for and follow up on interviews across industries.
Why I recommend it: Most interview prep here is built for engineers. This is the counterweight — plain-language guidance from the DOL that works for any field.
Applications for internships, part-time jobs, and full-time jobs in New York City's life sciences sector are open year-round. Includes a career summit, interview prep, and placement support.

Interview Prep
Ask the Experts: Nailing Your Technical Interview
Slide deck of advice from working technology architects and engineers: how to open strong, when to ask clarifying questions, what depth is expected at junior vs. senior level, and how to talk through architecture, scaling, and performance.
In plain terms: This slide deck shares advice from working tech professionals on handling technical interviews. Use it to learn how to explain your coding process, tackle tough questions, and tailor your answers for junior or senior roles.
Why I recommend it: Lead with your strongest projects — interviewers dig into whatever you highlight.
Slide guide to the tools that tell you what a role actually pays — Levels.fyi for role-level comp, Numbeo for cost-of-living context, Glassdoor for company intel — plus the mindset and mechanics of negotiating an offer.
In plain terms: This guide reviews tools for researching pay rates and local living costs. You can use it to determine your minimum compensation and prepare to negotiate your salary and benefits.
Why I recommend it: Pair one role-level pay tool with one cost-of-living tool before you ever name a number.
AI Resume & Interview Tool Picks (from the AI Job Search Tools guide)
The resume-writing and AI-interview sections of my AI tools guide: ATS-friendly resume builders and graders (Reactive Resume, Resume Worded, Rezi, Kickresume, Teal) plus mock-interview coaches (Yoodli, Exponent, Verve, Huru, Final Round).
In plain terms: This guide features free and low-cost AI tools for resumes and job interviews. You can use them to build and score ATS-friendly resumes or practice mock interviews with automated coaching.
Why I recommend it: Use the resume graders before you apply anywhere — the fastest wins usually come from fixing weak verbs and missing metrics, not from a new template.
Interview prep and career advice for developers from Fahim ul Haq, drawing on 15+ years in big tech.
In plain terms: A newsletter of coding interview prep and tech career advice from a longtime engineer and founder. Focused on interview patterns, system design, and growth in engineering roles.
From the site: Interview prep and career advice for devs. Tips and takeaways from 15+ years in tech.
Why I recommend it: Pair this with mock practice. The system design and interview breakdowns map closely to what big tech actually asks.
Huntr's data-backed look at resume formats — chronological, functional, and combination — and which structure holds up with recruiters and applicant tracking systems.
Why I recommend it: Format questions eat a lot of people's time. Read this once, pick chronological unless you have a real reason not to, and spend the rest of your energy on the bullet points.
WIRED report on candidates using AI to answer interview questions while employers use AI to screen and score them, and what that arms race does to hiring.
Why I recommend it: Know the screening you are up against, then be the human in the room. Over-scripted AI answers are exactly what these systems flag.
Newsletter breaking down system design and backend engineering concepts with clear diagrams — interview-grade explanations of how large systems work.
Why I recommend it: Use the diagrams as interview prep. If you can redraw one from memory and explain the tradeoffs out loud, you are ready to talk about it in a system design round.
People of Color in Tech's walkthrough of a realistic coding-interview study plan — what to prioritize, how to schedule practice, and how to prepare for the behavioral rounds alongside the technical ones.
In plain terms: This guide explains how to build a structured study plan for coding interviews. Use it to break down job descriptions, prioritize your practice topics, and prepare for recruiter screens alongside technical rounds.
From the site: Unlocking the coding interview opens the door to top pay, benefits, and perks at premier tech companies.
Why I recommend it: The plan structure is the value here. Scattered LeetCode grinding is why most people plateau.
A free self-paced curriculum for the Forward Deployed Engineer role — the person who sits with a customer and turns an AI model into a system that actually runs in production. 11 modules, 150+ topic articles, 700+ open-book questions and 15 daily drill questions, covering systems thinking, problem decomposition, LLM/RAG/agent architecture, data and event systems, physical AI and robotics, plus client discovery, integration, deployment and stakeholder management. It also publishes a map of 15 layers of the modern AI engineering stack drawn from real FDE and AI-engineer job specs, with links out to where to learn each one.
Why I recommend it: The whole curriculum opens without an account or a card — I checked — and an account only saves your progress. There is no pricing page anywhere on it, so nothing is being held back behind a paywall today. Worth knowing why this matters: 'Forward Deployed Engineer' is a job title that is actually being hired for right now, and it pays like engineering while rewarding the consulting side most engineers avoid. Two flags. It is one person's independent site, not an accredited course or a certificate anyone will recognize — the value is the material, not a credential. And it makes a strong claim, that foundation models are becoming a commodity and the money lives in the last mile; that is an argument, not a measured finding, so read it as a well-argued position.
A marketplace for coaching, classes, and community built to help ambitious people reach career and educational goals. Useful for structured mentorship and interview prep.

Why I recommend it: Huge back catalog — search it like a database when you hit a specific snag.
Free Workiva webinar for students on landing a software engineering internship: resume tips that clear automated screening, interview tactics, application deadlines, and a Q&A with current interns.
Details: If you are a student targeting an engineering internship, this is the kind of session where recruiters say out loud what they actually screen for. Go and take notes.
