Quantify and optimize team-match funnel

Company: Capital One

Role: Data Scientist

Category: Analytics & Experimentation

Difficulty: medium

Interview Round: Onsite

Treat team matching as a funnel. Define the key metrics (intro-to-meeting conversion, meeting-to-match conversion, average response time, variance), set weekly targets, and propose an experiment to improve match rate within 14 days (e.g., A/B test two recruiter outreach sequences). Specify success metrics, minimal detectable effect, sample size assumptions, decision boundaries, and what you will do if preliminary results are inconclusive.

Team-Matching Funnel: Metrics, Targets, and a 14-Day Experiment Plan

Context

You are designing analytics for a recruiting "team-matching" funnel that moves candidates from an introduction to a recruiter, to a meeting, and ultimately to a match with a team. Assume you can track timestamps for outreach and responses, and that you can run an A/B test across incoming candidate intros for 14 days.

Task

  1. Define the key funnel and timing metrics:
    • Intro-to-meeting conversion
    • Meeting-to-match conversion
    • Overall match rate
    • Average response time and its variance
  2. Set reasonable weekly targets for these metrics (state assumptions if needed).
  3. Propose a 14-day experiment to improve match rate by testing two recruiter outreach sequences (A/B):
    • Describe arms, eligibility, randomization, and guardrails.
    • Specify success metrics (primary/secondary), minimal detectable effect (MDE), sample size assumptions, decision boundaries, and what you will do if preliminary results are inconclusive.
