Coding Interview Assistant

The question is on your screen. So is the answer.

Coding problems, SQL prompts and take-home questions live on your screen, not in the audio. Press Alt+S and READSCREEN captures the question and suggests a worked answer — approach, edge cases and the reasoning you'd be expected to narrate.

# Problem

Given an array of intervals, merge all

overlapping intervals…

Suggested approach

Sort by start, sweep once, merge when current.start ≤ prev.end — O(n log n). Watch the equal-boundary edge case.

READSCREEN

One shortcut from question to approach

Live assistants that only listen miss the most important part of a technical round: the problem statement on screen.

Press Alt+S and READSCREEN captures what's on your screen — a coding platform, an SQL prompt, a take-home brief — and turns it into a question Interviewdom can work with.

No retyping the problem while the clock runs.

Worked solutions

Reasoning you can narrate, not just a final answer

Interviewers grade the journey — pasting a correct answer you can't explain helps nobody, least of all you.

Suggestions come as a worked solution: the approach, the complexity, the edge cases, and the reasoning behind each step — the same things you'd be expected to say out loud.

You learn the pattern, not just this one problem.

Worked answer

ApproachSort intervals by start, then sweep once.
ComplexityO(n log n) time, O(n) space.
Edge casesEqual boundaries, single interval, empty input.
NarrationWhat to say out loud while you code it.

System design

Architecture diagrams, generated on demand

System-design rounds reward structure, but whiteboarding from a blank page under pressure is brutal.

For system-design questions, Interviewdom generates Mermaid architecture diagrams — components, flows and the shape of the system — so you can spend the round discussing trade-offs.

You walk the interviewer through a design instead of drawing one.

Interviewdom generates architecture diagrams for system-design questions, so you can narrate the trade-offs instead of drawing boxes from scratch.

Practice mode

Drill real problems before the real round

Grinding problem lists without feedback tells you what you got wrong, not why.

Use READSCREEN against practice problems and mock interviews: capture the question, compare your approach with the suggested one, and review the scored report afterwards.

Every practice session compounds.
