##### Question In 45 minutes, design an end-to-end system (it need not be travel-related) and present a low-fidelity wireframe. Your deliverable should cover: Problem statement and target users (start by asking clarifying questions). Core user journeys and MVP feature set. Screen flow or sketch of the low-fi wireframe. Success metrics and key trade-offs. High-level technical considerations for an initial launch. ##### Hints Timebox each section; prioritize the riskiest assumptions. Explicitly state any assumptions you make while clarifying requirements.

This question evaluates a candidate's competencies in product design and decision-making, including problem framing, user-journey definition, MVP prioritization, low-fidelity wireframing, metric selection, trade-off articulation, and high-level technical considerations.

Product Design Exercise: End-to-End System (with Low-Fi Wireframe)

Design an end-to-end system (it does not need to be travel-related). You have 45 minutes. Your deliverable should include the following sections:

Problem Statement and Target Users

Start by asking clarifying questions.
Explicitly state any assumptions you make.

Core User Journeys and MVP Feature Set

Identify the primary workflows.
Define the smallest feature set to validate the riskiest assumptions.

Screen Flow and Low-Fidelity Wireframe

Provide a simple screen map and rough wireframes/sketches.
You can use text/ASCII to outline the layout.

Success Metrics and Key Trade-offs

Define a North Star metric and supporting metrics.
Call out the most important trade-offs.

High-Level Technical Considerations for Initial Launch

Architecture, data, integrations, constraints, and risks.

Hints:

Timebox each section (e.g., 5–10 minutes each) and prioritize the riskiest assumptions.
Explicitly state assumptions if requirements are ambiguous.

Suggested clarifying questions to consider:

Who are the primary users? What problem are we solving for them now vs. later?
What platforms (web, iOS/Android) and geographies are in scope for MVP?
What business model and constraints (privacy, compliance, integrations) apply?
What is the desired North Star metric and any guardrails?
What existing systems or third-party integrations are available?
