Where Uber puts the most pressure

The stage distribution tells candidates where the loop concentrates effort and what kind of reasoning tends to matter most in each round.

Phone Screen

10 records

Initial interviews typically probe statistical understanding and problem-solving with brief coding or SQL exercises.

Technical Interview

9 records

Longer sessions focus on SQL queries, A/B testing, metrics, and modeling scenarios to assess analytical depth.

Take Home

2 records

Assignments involve practical coding, driver incentives, or data extraction tasks, testing real-world problem-solving skills.

How to prepare for Uber

The prep layer should stay practical: what to review, which interview themes recur, and how GhostInterview fits the live round instead of just prep week.

Prep focus

Review probability, statistics, and experimentation concepts
Practice SQL queries and pandas-style data manipulation
Understand modeling approaches and feature engineering considerations

Use GhostInterview during the actual interview

GhostInterview is not just for prep. Use it during live interview loops and follow-up pressure while the conversation is still happening. On supported platforms, the overlay is designed to stay hidden on screen share.

Activate stealth mode to view candidate responses unobtrusively
Use GhostInterview during experimentation and modeling discussion to keep trade-offs, caveats, and follow-up answers organized.
Use GhostInterview with its stealth-first workflow so the guidance stays off supported screen shares while you handle deeper stakeholder or technical questions.

Related Interview themes

These are the recurring interview themes worth reviewing before a similar loop.

Statistics

Core for evaluating probability, distributions, and analytical reasoning in DS interviews.

Experimentation

A/B testing questions measure ability to assess causality and interpret metrics correctly.

Probability

Essential for problem-solving, experiment design, and risk evaluation in analytical tasks.

FAQ

What is the dominant interview stage at Uber for Data Scientists?

Phone Screen is the most frequent stage, often used to assess fundamental statistics and problem-solving skills.

Which topics appear most often in Uber DS interviews?

Statistics and experimentation, SQL and data manipulation, and modeling with machine learning are highly recurring.

Are take-home assignments common for Uber DS roles?

Take-home tasks are less frequent but focus on real-world coding, driver incentives, or complex data extraction problems.

What coding skills should I prioritize?

Strong SQL proficiency and familiarity with Python/pandas data manipulations are crucial for technical interviews.

Can GhostInterview help during the actual Uber interview?

Yes. Use GhostInterview during live coding rounds, system design discussion, and follow-up pressure while the interview is happening. On supported platforms, the overlay is designed to stay hidden on screen share.
