How CoderPad Enterprise's Anti-Cheat Detects AI Tools
CoderPad Enterprise is the round most candidates worry about. It is also, in our reading, the single best-engineered anti-cheat surface in the live-coding-interview category. This post is a forensic walkthrough of how t…
Defending an AI-Assisted Answer: A Talking-Points Playbook
The catch is rarely the overlay. The catch is the follow-up. Interviewers in 2026 stopped looking for the tool. They look for the candidate who can't explain the code that just appeared on the editor. That detection vec…
12 Algorithm Patterns: Talking Points for AI-Assisted Code
This post is the tactical pattern catalog. For the four-phase psych framework that wraps it (Internalize → Explain → Defend → Modify), see the sibling Defending an AI-Assisted Answer: A Talking Points Playbook. Together…

How Proctor Content Scripts Work — and Why Browser AI Fails
Every modern coding-interview proctor — HackerRank, CoderPad, CoderPad Enterprise, CodeSignal, Karat — ships JavaScript that runs inside the candidate's tab. It is not hidden. You can see it in DevTools' Sources panel,…
Test Any AI Interview Tool in 60 Seconds (Free Simulator)
We do not want you to take our word for it. The category is full of tools that promise stealth and ship a single user-mode flag. Reviews are unreliable because the tools that fail are the loudest about their stealth. So…
I Bought 14 AI Interview Tools. Here's the Brutal Truth.
Fourteen AI interview copilots across five categories: coding-interview specialists, LeetCode-specific tools, behavioral-specific tools, resume + cover letter + interview bundles, and generic AI overlays. We tested ever…
LockedIn AI vs FaangCoder: $1,499 vs $399 [Honest Test]
Two lifetime AI interview copilots. Both promise stealth. One costs $1,499. The other costs $399. We bought both, ran them side by side on Windows for 60 days across HackerRank, CoderPad, CodeSignal, and a Karat-style m…

Four Stealth Layers FaangCoder Stacks at the Windows Kernel
Most AI interview tools in 2026 ship one stealth feature: they call SetWindowDisplayAffinity with WDAEXCLUDEFROMCAPTURE and call it a day. That's a single bit, set in user mode, on a flag every modern proctor knows to q…
Ring-0 Memory Read vs Screen-Capture OCR — Deep Dive
Every other AI interview overlay shipping in 2026 reads its input the same way: take a screenshot, run it through OCR, hand the resulting text to a model. FaangCoder does not do that. We attach to the IDE or browser pro…
WDDM and the Windows Display Pipeline — A 30-Minute Tour
If you build AI tools that paint pixels on Windows — overlays, capture tools, recording software, anything that has to coexist with the desktop compositor — you should be able to draw the WDDM stack on a whiteboard from…
Why FaangCoder Ships Nothing on macOS (And Might Never)
The most common email we get reads, in some variant: "Will you ship a Mac version?" The answer is no. Not "no, not yet" — no, with an asterisk for "we might in some hypothetical future where Apple's platform model meani…
Microsoft Attestation: Why Stealth Drivers Are a Moat
If you want to load a kernel driver on a current consumer Windows install — Windows 10 1607 or later, or any version of Windows 11 — Microsoft has to sign it first. Not "Microsoft has to trust the cert"; not "you can se…
Blind 75 vs NeetCode 150: 800 Interviews Tracked, One Wins
Three lists dominate FAANG prep advice. Blind 75, the original from a 2020 Blind post by an ex-Facebook engineer. NeetCode 150, the expanded list curated by the YouTube channel of the same name. Grind 75, an algorithm-d…
12 Ways ChatGPT Quietly Killed Your FAANG Interview
ChatGPT shipped in November 2022. By March 2023, every FAANG hiring committee had watched a candidate solve LeetCode Hard problems in under three minutes by paste-and-pray. By Q4 2023, the panic crystallized into policy…

Should You Use AI on a Coding Interview? Decision Tree
There are two kinds of post on this question online. The first kind is a sermon — "real engineers don't cheat" — written by people who do not have a FAANG offer at stake on Friday. The second is a sales pitch — "use thi…
Using AI on a HackerRank Assessment Without Flags (2026)
HackerRank is the volume platform. More candidates run into HackerRank than any other coding-interview surface — phone screens, take-home assessments, certifications, full Skills Assessments. It is also the platform whe…

behavioral-prep
Senior engineers underprep for behavioral and then lose offers on it. In 2022 it carried 25% of loop signal. In 2026 it carries 35-40%. ChatGPT did this. Coherent narrative under live follow-up questions is the one thin…
11 AI Coding-Interview Tools Tested. Only 3 Aren't Garbage.

binary-search-pattern-guide
You think you know binary search. Then the array isn't sorted, the bounds are off-by-one, or the "array" is actually a continuous answer space you have to invent. You freeze. About 60% of senior FAANG candidates write o…
cluely-alternatives
You tried Cluely for FAANG interview prep and it left you cold. You're not alone. Cluely positions itself as a generic AI overlay. Meeting bot, search assistant, "see the world through AI." That works for sales calls an…
comp-bands
Don't know your level's comp band? You'll leave $50K-$200K on the table when you accept your offer. The 2026 bands are higher than 2022 across the board (post-AI talent crunch + inflation + Anthropic/OpenAI/Stripe pulli…

AI Interview Subs Are a $3,576 Trap. Here's the Math.
Most AI interview tools charge between $39 and $149 a month. Every month. Forever. The math works out to $400 to $1,800 across a typical FAANG prep cycle. Across two cycles (one for this job, one for the next) it's $800…
system-design-faang
System design is the FAANG round that separates engineers from senior engineers. In 2022 it was an L5+ filter. In 2026 it shows up at L3-L4 phone screens (in scaled-down form), and at L5+ it's two rounds, not one. The 2…
tools-that-get-you-caught-vs-tools-that-dont
Some AI interview tools survive 2026 proctoring. Others get you flagged in five minutes. The difference isn't the marketing copy. It's the architecture. Tools that live inside the browser get caught. Tools that live out…
top-75-leetcode-faang-frequency
The original Blind 75 list, posted on Blind in 2020, was an opinionated curation by an ex-Facebook engineer. Excellent for its era. By 2026 it's six years stale. Half the problems on it remain top-frequency. The other h…
