ASSIGNMENT: GX-250505
YOUR ROLE: Product Experimentation Analyst
WORKLOAD: 8–12 hours
COMPLEXITY BAND: Decision

01 / SITUATION

THE OPERATING MOMENT

The decision is already in motion.

A mobile experiment appears promising, but exposure, assignment, behavior, and commercial outcomes do not arrive at the same grain.

YOUR MANDATE

Build the experiment cohort, quantify effect and uncertainty, test the result’s credibility, and recommend rollout, iteration, or restraint.

02 / OPERATING CONDITIONS

WHAT THE WORK DEMANDS

Interrogate before you recommend.

You receive access to a bounded part of Meridian’s synthetic enterprise estate. The briefing defines the decision—not the analytical path or a preferred answer.

SQL / EVIDENCE CONSTRUCTION

Establish the facts.

Build one row per assignment and reconcile exposure, sessions, events, and orders.

PYTHON / ANALYTICAL JUDGMENT

Stress-test the decision.

Run balance checks, estimate effects and uncertainty, inspect distributions, and separate confirmatory from exploratory slices.

BEFORE YOU ACCEPT

Know the neighborhood.
