Why peeking inflates false positives
A PM checks the experiment dashboard every morning and wants to ship as soon as p < 0.05. What is the main problem with this policy?
Interview field notes · issue 01
Practice the decisions interviews are really about.
Diagnose a funnel, design an incrementality test, pick the north-star metric, rank the roadmap, or prove an AI agent works. Each question is graded against a model answer written the way strong candidates answer.

What Uplift is
Uplift is an interview-practice platform for analytics, experimentation, product and AI roles. You answer interview-style questions in the format the interview uses: SQL against sample tables, multiple choice, a computed number, or a written case. Each submission is graded against an answer key or rubric. Hints unlock one at a time, attempts are unlimited, and the model answer stays hidden until you ask for it. Read how grading and the leaderboard work.

How a session works
Step 1
Pick a branch
Choose from eight skill tracks, called branches, covering the work analysts, product managers and marketing teams are actually interviewed on.
Step 2
Answer under constraints
Run the query and inspect the rows it returns, pick the option, compute the number, or structure the case in prose. Unlimited attempts.
Step 3
Compare against the model
Submissions return checks and pass/fail feedback; the model answer and its reasoning stay hidden until you ask to see them.
