  • Researchers + UX writers transitioning into product design.

Why Coachingle for Design

What separates us from the problem-banks + recorded courses.

Portfolio walk-through drills

Upload a case study; the AI walks it the way an interviewer would, asking 'why this metric', 'what did you cut and why', 'what would you do differently'.

Design exercise + critique

60-minute timed exercises — design a feature, defend tradeoffs, sketch flows. Get a critique that grades problem-framing, exploration, and craft separately.

Senior + Staff rubrics

Senior IC interviews grade craft + collaboration; Staff interviews grade design-strategy + cross-team influence. The interviewer's bar shifts.

Spaced-rep on heuristics

10+ Nielsen heuristics, Hick's law, Fitts's law, mental models — surfaced as flashcards on the spaced-rep schedule. The fundamentals stick.

What you'll cover

Concept coverage drilled across cheatsheets, flashcards, quizzes, and mock interviews.

  • Portfolio narrative + case-study structure
  • Design exercise: feature design, redesign, jobs-to-be-done
  • Design rationale + tradeoff defense
  • Heuristics: Nielsen, Hick, Fitts, Miller, Tesler
  • Mental models + information architecture
  • Cross-functional collaboration (eng / PM / research)
  • Design ops: critique, hand-off, design systems
  • Behavioral: difficult feedback, conflict, growth

Frequently asked questions

Can the AI actually critique a case study?

Yes — upload PDFs or paste case-study links and the AI grades problem-framing, exploration breadth, decision rationale, and craft separately. It's strict in the way a staff designer would be, not vague.

Do you do design exercises live?

Yes. 60-minute timed exercises — you sketch + narrate, AI follows up. We don't render the canvas (use Figma); but the interview-loop dialogue is full.

Are research / UX-writer roles covered?

Not in v1. We focus on product-design IC roles. Research + writing tracks are on the roadmap once we have validated demand.
