12 patterns — sliding window, two-pointer, DP, and more — with the anti-pattern phrase, the strong-candidate phrase, and the follow-up to expect for each.

Why FaangCoder reads problem text from process memory at the kernel — and why every screen-capture-then-OCR pipeline is slower, lossier, more visible.

FaangCoder's /proctor simulator runs the same vectors a real proctor uses — keystroke, focus, screen-capture. Test any AI tool in 60 seconds.

What every layer of the Windows graphics stack does — application surface to display miniport — and where screen-capture can be filtered.

Apple's kext deprecation, SIP, and ScreenCaptureKit — the structural reasons a stealth-grade interview overlay can't reach kernel depth on macOS.

EV code-signing, Microsoft HLK, attestation vs WHQL, the Dev Portal flow — why this multi-month gauntlet is the real moat for stealth drivers.

41% of devs run Windows but 90% of stealth interview guides assume Mac. Here's the 10-step Windows-native setup FAANG candidates use in 2026. Bookmark it.

Cluely costs $79/mo and isn't built for coding interviews. We tested 9 coding-tuned alternatives in 2026. The #1 pick is $399 lifetime and beats every sub.

https://faangcoder.ai/blog/does-coderpad-detect-ai-usage 2026-05-03T00:00:00Z 2026-05-05T00:00:00Z

CoderPad runs 4 AI detection vectors in 2026 and most tools trip 2+ of them. We tested 8 against live FAANG rounds. Only 1 scored a perfect 4/4 GREEN.

https://faangcoder.ai/blog/does-codesignal-detect-ai 2026-05-03T00:00:00Z 2026-05-05T00:00:00Z

CodeSignal runs 5 detection vectors including biometric typing analysis. We tested 8 AI tools and only 1 hit a clean 5/5 GREEN. The rest got candidates flagged.

https://faangcoder.ai/blog/does-hackerrank-detect-ai 2026-05-03T00:00:00Z 2026-05-05T00:00:00Z

HackerRank runs 6 detection vectors against AI in 2026, and 7 of 8 tested tools tripped at least one. The forensic teardown plus the only tool that scored 6/6.
