Invisable and Private AI coaching for Interview Practice

Interview Practice Coach

A desktop practice assistant for coding interview prep, built around captured prompts, progressive hints, complete solutions, usage credits, and account-managed access.

Captured prompt
Design a cache with fast reads, writes, and eviction. Explain edge cases and complexity.
Coach response
Start by identifying the invariant: the newest item must be cheap to promote and the oldest item cheap to evict. A hash map plus linked ordering gives both operations in constant time.

Response window preview

The response window is compact, readable, and built for practice review: switch between hints and full solution mode, scan reasoning quickly, and keep account usage separate from the desktop workflow.

Responses are designed for Invisable and Private practice workflows and local display controls. Visibility in screen sharing or recordings depends on operating system and meeting app behavior, so use the coach only where assistance is permitted.

Progressive hints

  1. Track recency separately from lookup.
  2. Use a map for key access and an ordered list for eviction.
  3. When a key is read, move it to the most recent position.

Reasoning snapshot

A hash map gives constant-time lookup. A linked order gives constant-time promotion and removal when each node stores neighbor pointers.

Built for focused interview prep

Use the coach during practice sessions to turn prompts into structure, hints, and reviewable reasoning while keeping billing and usage state on the backend.

?

Progressive hints

Ask for staged nudges before revealing a full solution, so practice stays active instead of becoming answer copying.

{}

Complete solutions

Switch to solution mode for reasoning, edge cases, complexity, and implementation guidance in the language you choose.

[]

Prompt capture workflow

Analyze captured coding challenge prompts and optional notes from the desktop app without manual retyping.

$

Usage credits

Free trial requests, paid credits, day passes, three-month passes, and monthly plan balances are enforced by the Worker.

@

Google login

The backend owns OAuth, creates signed sessions, and returns this page to account details instead of redirecting to the desktop app.

+

Referral credits

Each account gets a referral link and referral history, with backend-granted credits for eligible new-user referrals.

Invisable and Private practice display

Response-window controls are designed for focused local practice. Sharing and recording visibility depends on the meeting app and operating system.
