Technical interviews
Hear the problem. See the solution.
CoderCue listens to both sides of the call, reads the problem off your screen, and returns a complete function with its complexity — while you are still talking through the approach.
Pattern hash map, single pass
def two_sum(nums, target):
seen = {}
for i, n in enumerate(nums):
need = target - n
if need in seen:
return [seen[need], i]
seen[n] = i
return []Time O(n) · Space O(n)
The answer panel. Every solution arrives highlighted, with its bounds, ready to type or say.
Why it is hard
An interview is 45 minutes of thinking out loud
You are asked to solve something you have not seen, narrate your reasoning, hold the constraints in your head and stay personable — all at once, with someone watching everything you type.
Almost nobody fails because the problem is impossible. People fail because the pressure collapses the time they have to think, and the obvious approach is not the one that arrives first.
The clock beats you
A brute force that works in four minutes beats an optimal solution you are still deriving when time is called.
The follow-up is harder
Naming the technique matters as much as the code. "It is a sliding window" is half the credit.
You blank on the bound
You wrote it correctly and cannot say why it is O(n). That is a point lost on a solution you already had.
The problem is on screen
It is pasted into a shared doc, a terminal or a test harness — not read aloud to you cleanly.
Every feature
What is actually in the box
No add-ons, no per-seat maths, no "contact sales". One purchase, the whole thing.
Hears both sides
Your microphone and the call audio are captured as two separate streams, so YOU and the INTERVIEWER are labelled correctly from the first second. No voice-printing, no virtual cable.
Full code answers, not hints
Every response is a complete function in a fenced block with its language tag — signature, body and return. No pseudo-code, no ellipses to fill in under pressure.
Syntax highlighting
Keywords, types, strings, numbers, calls and comments are coloured across C#, Java, Python, C++, SQL and JavaScript, so a solution is readable at a glance rather than parsed.
Complexity on every answer
Time and space in O(...) notation on one line, plus the line or operation that sets the bound. The thing you get asked to justify, already justified.
Solves a screenshot
The problem is on your screen and not in the conversation? Press Ctrl+Alt+S and the panel reads it and answers it.
Reads your resume
Attach your CV once. When the interviewer asks about your experience, answers come from your real employers, projects and numbers — in the first person, without inventing anything.
Grounds in your own material
Add notes, a job description, past feedback or a company's engineering blog. CoderCue answers from those first and says so when it falls back to general knowledge.
Eleven interview playbooks
Algorithm Coach, System Design, Complexity Radar, Bug Hunter, Take-Home Review, Behavioural/STAR and more. Each shapes the output for that round rather than answering generically.
Delivery coaching
A playbook that watches only your own turns and tells you when you are hedging, going quiet, or coding without stating the approach first.
Out of every screen share
The window is excluded from capture at the OS level, so it is fully visible to you and absent from Teams, Zoom, Meet, Discord, OBS and the Snipping Tool.
Taskbar and Alt+Tab too
Hide the app from the taskbar and the Alt+Tab switcher, so it is not listed anywhere on screen while you are sharing it.
Your key, your machine
Bring a DeepSeek or any OpenAI-compatible key. It is stored encrypted on your PC, never sent to us, and transcription works offline.
How it works
Set up once. Then never touch it again.
Three steps, about two minutes, and no configuration during the interview itself.
Add your AI key
Settings, Reasoning. Paste a DeepSeek key (cheapest) or any OpenAI-compatible endpoint and press Test. It stays on this machine, encrypted.
Pick your audio
Choose the microphone and the call output, and watch the meters move when you speak. Both streams matter: one is you, the other is the interviewer.
Start the session
Pick a playbook and press Start. Answers arrive about a second after each point, in your voice, with the code highlighted and the bounds stated.
Invisible plan
Invisible to screen capture.
Not to you.
Screen sharing a window is a request, and Windows lets an application decline it. CoderCue uses the same display-affinity API streaming players use to keep protected video out of a recording — with one difference: the window stays perfectly readable on your own screen.
- Absent from OBS, Xbox Game Bar and any desktop recording
- Absent from Discord, Zoom, Teams, Meet and Webex screen shares
- Removed from the taskbar and the Alt+Tab switcher
- One click to drop the invisibility when you want to show someone
- Nothing to install underneath — no driver, no kernel component
What it covers: software capture on this machine. Recordings, screen shares and streaming tools receive an empty region. A camera pointed at your monitor is hardware, and sits outside any software's reach.
What a screen share sees
Capture APIs receive an empty region where this window is. The desktop behind it comes through normally.
What you see
Your answer
"Move the pointer at the smaller value. When the pair matches the target, you are done — O(n) time, O(1) space."
