The New Way to Showcase Software Skills: Proof of Work in the AI Era

The resume, the degree, the keyword-stuffed LinkedIn, and the LeetCode grind all broke as trust signals the moment AI made them fakeable. Here is what recruiters actually check in 2026, and the 30-day playbook to show it.

The AI Data & Alignment Interview

Rating and improving model outputs, annotation, RLHF preference data, evaluation, red-teaming, is the fastest-growing on-ramp into AI, and it rewards careful reading and clear writing over an ML degree. Here's how to get competent and get hired.

The AI / LLM Engineering Interview

AI engineering interviews in 2026 aren't about implementing backprop. They're about designing a RAG pipeline, proving it works, and keeping it cheap and safe in production, on top of a model you can't see inside. Here's the real question set.

The Advanced JavaScript Interview

Senior, staff, and principal JavaScript interviews are barely about 'what prints.' They're about what breaks at scale, how you'd know, and the trade-off you're knowingly accepting. Here's the real question set.

The JavaScript Beginner Interview

A junior JavaScript interview isn't a vocabulary test. It's 'here's a snippet, tell me what it prints and why.' Here are the questions that actually come up, attempt each one, then reveal a full answer.

The JavaScript Intermediate Interview

Mid-level JavaScript interviews stop asking for definitions and start asking you to predict microtask order and implement debounce, bind, and memoize from scratch. Here's the real question set, attempt, then reveal.

Things I Learned Doing a Master's I Swore I'd Never Do
