Recently put together a Zoox , as a self-driving company under Amazon, the interview style is a bit different from the traditional big companies, which will investigate the conventional programming and algorithmic ability, but also include some system design, scenario reasoning, and even domain knowledge questions. The overall feeling is that it is very technical, but at the same time, it also pays attention to how the candidate expresses his thoughts and solves the problem logically. For students preparing for Zoox interviews, the e-interview is considered a "threshold" link, which can not only screen the basic skills, but also reflect whether you are suitable for their fast-paced team atmosphere.
Overview of the Zoox interview process
A Zoox interview typically consists of the following stages:
- HR call screening
- Understand the candidate’s background, project experience and job motivation
- Confirm basic matching, such as technology stack and educational experience
- The purpose is to determine whether to enter the technical stage
- Technical phone/electronic surface (Coding & System Design)
- Core examinations include algorithmic ability, programming basics, and logical reasoning.
- May involve Leetcode intermediate-to-higher difficulty questions
- System design issues often related to autonomous driving or embedded systems
- Some interviews may require discussion of distributed computing or performance optimization
- Behavioral aspect & project aspect
- Candidates need to introduce past project experience, focusing on technical implementation and decision-making logic
- Evaluate communication skills, teamwork skills, and fit with Zoox corporate culture
- Senior management interview/VP interview (optional)
- Sometimes only short exchanges or company visits are arranged
- Mainly understand the candidate's overall career plan and understanding of the company's business
Zoox Interview Record
Zoox interview real questions (experience sharing)
The following content is based on the real experiences of multiple candidates and is compiled from public data sources for reference only.
Round 1: Algorithms and Data Structures
- Reverse Linked List: Examine both recursive and iterative implementations
- Stock buying and selling problem (parallel computing on multiple machines): The interviewer tests the understanding of parallel computing and optimization algorithms
- Leetcode 4: Find the median of two sorted arrays
- 2D matrix minimum path sum (including negative cost): First implement dynamic programming (DP), and then verify the DFS recursive implementation
Tip: Zoox likes to test candidates’ ability to express ideas, and it is recommended that you continue to verbalize your logic during the problem solving process.
Round 2: Mathematical Logic & Scenario Reasoning
- Find perimeter of hexagon area
- Moon distance estimate
- Changes in the water surface after throwing a ball in a boat in a swimming pool
- During the interview process, there will also be a relaxed communication time to test the candidate's thinking flexibility and communication skills.
Tips: Logical reasoning questions not only test mathematical abilities, but also reflect Zoox’s emphasis on engineering intuition.
Round 3: Project and professional background discussion
- Interview with senior managers, focusing on project experience
- Pay attention to why candidates choose the field of autonomous driving and the reasons for technology selection
- May involve in-depth questions from the Vision/ML group, occasionally asking about embedded systems knowledge
It is recommended that the core technical points and challenges of each project be summarized during the preparation stage, and the problems, plans and final results can be clearly described.
Round 4: Executive interview/VP interview (optional)
- Invited to visit the company and learn about the team’s working environment
- Mainly understand the candidate’s overall background and career plans
- Depending on the situation, technical questions may not be asked
Zoox interview experience summary
- Technical questions are fast-paced and large, requiring rapid analysis and clear expression.
- Scenario reasoning questions test comprehensive thinking ability and innovative ideas
- The project aspect emphasizes clear logic, results orientation and technical depth.
- The behavioral and executive aspects focus on communication, collaboration skills and cultural fit.
According to Glassdoor statistics, the average length of Zoox technical interview is about 1 hour per round, the overall process is 3-5 rounds, and the interview difficulty is medium to high.
