GhostDesk
The stealth AI copilot engineered for high-stakes technical interviews & proctored OAs. GhostDesk floats invisibly above HackerRank, CodeSignal, Zoom, & Teams — delivering sub-second LeetCode solutions, complexity analysis, and live voice teleprompting without stealing window focus.
Design a data structure that follows LRU constraints. Implement get and put in O(1) time complexity.
Talking Points: "We use a HashMap + Doubly LinkedList to ensure O(1) get & put operations..."
# Optimal LRU Cache Solution
class LRUCache:
def get(self, key):
# O(1) map lookup
def put(self, key, val):
# O(1) move to headInvisible to the interviewer. Glowing on your screen.
During Zoom, Teams, Google Meet, or CodeSignal screen shares, GhostDesk stays 100% invisible on the shared stream while streaming live code answers on your display. Drag the slider to compare.

Design a data structure that follows LRU constraints. Implement get(key) and put(key, value) in O(1) average time complexity.
Explain to interviewer: 'We use a HashMap combined with a Doubly LinkedList. The HashMap gives O(1) key lookups, while the Doubly LinkedList allows O(1) node removal and insertion at the head.'
class Node:
def __init__(self, k, v):
self.key, self.val = k, v
self.prev = self.next = None
class LRUCache:
def __init__(self, capacity: int):
self.cap = capacity
self.cache = {} # key -> node
self.head, self.tail = Node(0, 0), Node(0, 0)
self.head.next = self.tail
self.tail.prev = self.head

GhostDesk was built from the ground up to ensure your AI copilot stays 100% undetected during live technical & behavioral interviews.
Given an array of integers nums and an integer target, return indices of the two numbers that add up to target.
Example 1:
Input: nums = [2,7,11,15], target = 9
Output: [0,1]

OS-Level Capture Exclusion
Hardware display capture exclusion renders GhostDesk 100% invisible to Zoom, Teams, Meet, CodeSignal, HackerRank, & screen recording software.
Zero-Window Proctor Scanner Evasion
Aggressive proctoring platforms (HackerRank, CodeSignal, Mettl) scan for active third-party windows. GhostDesk completely cloaks its window frame and display layer, passing scans with 0 windows detected.

Process & System Camouflage
GhostDesk camouflages its process tree as a verified system background service. Searches in Task Manager yield 0 matches for GhostDesk, while process monitors see only a quiet background service running at 0.1% CPU.
Hardware Raw Input Hotkeys & 5ms Panic
Global shortcuts are captured at the hardware input layer without stealing browser focus or triggering blur events. Hit Ctrl+Shift+Q for an instant 5ms panic hide, or Ctrl+Shift+S to solve instantly.
Taskbar & Alt+Tab Invisibility
GhostDesk never appears in the Windows taskbar, system tray, or Alt+Tab switcher. Switch between your browser and editor with zero visual trace of an AI copilot.
Engineered beyond competitor limitations
Traditional interview assistants run on basic uncloaked window frames that trip HackerRank and CodeSignal proctor scans. GhostDesk is engineered with low-level display cloaking.

Undetected on every interview platform
Daily hardware verification confirms GhostDesk stays completely invisible on screen share during live video calls, proctored environments, and recording tools.
Passes CodeSignal Pre-Screening and live assessment proctoring. Hardware capture exclusion guarantees webcam/screenshare zero-leak, while click-through ensures you never lose focus in the browser IDE.
Tested against HackerRank desktop client and proctor scanners. GhostDesk cloaks its window frame and display layer, passing scans with 0 windows detected while capturing questions cleanly.
Full click-through transparency. Interact with CoderPad's editor and terminal without closing or moving GhostDesk. Zero tab switching or window blur events.
Direct OS-level capture exclusion. Interviewers see your entire desktop, code editor, or browser without a single pixel of GhostDesk ever appearing.
Bypasses Teams desktop and browser screen-sharing pipelines. Completely excluded from full-screen share and application window capture.
Desktop capture pipelines ignore GhostDesk at the hardware display compositing layer. Full screen presentation shows zero HUD trace.
One-click visual capture grabs problem descriptions, test cases, and constraints. Sub-second high-speed intelligence outputs optimal time/space complexity solutions.
TestGorilla monitors window focus loss and mouse exits. GhostDesk's hardware shortcut processing and click-through mode allow problem solving without triggering browser blur listeners.
Bypasses Proctorio's screen recording and secondary monitor checks. Operates completely outside the browser's permission and extension boundaries.
Engineered for Karat's fast-paced 45-minute live technical screenings. Gives instant bug fixes, code refactorings, and multi-file architecture explanations.
Hardware overlay exclusion renders GhostDesk completely invisible to Webex desktop and meeting capture drivers.
Used extensively by Amazon loop candidates. GhostDesk provides invisible real-time LP (Leadership Principles) talking points and coding support.
Screen streaming on Discord and Slack huddles passes cleanly through hardware capture exclusion without any overlay artifacts.

Common questions
GhostDesk is the #1 undetected AI interview copilot for Windows. It floats invisibly above any application during Zoom, Teams, Google Meet, CodeSignal, and HackerRank sessions — streaming real-time LeetCode solutions, space/time complexity explanations, and voice interview teleprompter answers.
No. GhostDesk uses hardware-level OS capture exclusion to exclude itself from all OS capture pipelines. Interviewers see a completely clean screen share with zero AI widgets.
Yes. In v2.6.0, GhostDesk features Zero-Window Proctor Cloaking specifically engineered for HackerRank and CodeSignal. It strips window frames, clears titles, and completely cloaks its display layer, passing native desktop proctor scans with 0 detected windows. Additionally, test questions are captured accurately even on restricted assessment windows.
No. GhostDesk camouflages its process tree as a verified Windows system background service. Searching for 'GhostDesk' in Task Manager returns 0 results, and process monitoring tools observe only a quiet, trusted Windows background service running at 0.1% CPU.
Unlike competitor tools that rely on basic uncloaked window frames that trip proctor scans, GhostDesk was built from the ground up with low-level display cloaking, sub-800ms response speed, hardware shortcut hooks (no tab blur events), and accessible $10 passes instead of $50-$100/month recurring subscription traps.
No. GhostDesk generates visual text answers and silent teleprompter prompts directly on your overlay. You can also route voice audio to a private earpiece.
Sub-second. GhostDesk utilizes an ultra-low-latency intelligence engine for code generation, returning complete solutions and talking points in under 800 milliseconds.
Start a test Zoom call or record your desktop using OBS Studio / Windows Game Bar (Win+G). When you view the recorded video or test stream, GhostDesk will be 100% invisible.
