How to Pass the Vay Software Engineer Interview in 2026
The Vay DNA (TL;DR)
The Vay Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Vay interview outcomes, avoid these common traps:
- Blaming the other party or portraying them negatively.
- Focusing only on the disagreement and not the resolution.
- Describing the disagreement without detailing the resolution process.
- Not understanding or acknowledging the other party's perspective.

9 of 21 questions shown
Recruiter Screen
1- 1
Type · Motivation
What interests you about working on autonomous driving technology at Vay, and how do you see your skills contributing to our mission?
Coding Screen
3- 2
Type · Algorithmic
Given a stream of sensor data (e.g., lidar points, camera frames) representing a simplified 2D environment, design an algorithm to detect and track moving objects. Assume you have helper functions to process individual sensor readings. - 3
Type · Algorithmic
Implement a function that takes a list of detected objects with their bounding boxes and timestamps, and determines if any two objects have collided within a given time window. Assume bounding boxes are axis-aligned rectangles. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · System Design
Design a real-time system for detecting and reporting safety-critical events (e.g., sudden braking, swerving, potential collisions) from a fleet of autonomous vehicles. Consider data ingestion, processing, and alerting. - 5
Type · System Design
Design a system to efficiently store and query historical sensor data (lidar, camera, radar) from Vay's vehicles for offline analysis and model training. Consider data volume, access patterns, and cost. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · Coding
Write a robust function to parse and validate incoming vehicle status messages (JSON format). The schema can be complex, with nested objects and various data types. Handle malformed messages gracefully. - 7
Type · Coding
Implement a thread-safe queue for passing sensor data between different processing modules in the vehicle's software stack. Ensure high throughput and low latency. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
11- 8
Type · Past Experience
Tell me about a time you had to influence a team or stakeholder who was resistant to your idea or direction. What was the situation, what did you do, and what was the outcome? - 9
Type · Collaboration
Tell me about a time you had a significant disagreement with a cross-functional partner (e.g., engineering, design, operations). How did you approach resolving it? - + 9 more questions in this round (sign up to unlock)

Sample answers
What a strong answer to these Vay interview questions shows.
Tell me about a time you had to influence a team or stakeholder who was resistant to your idea or direction. What was the situation, what did you do, and what was the outcome?
A strong answer shows: Influence and persuasion skills; Stakeholder management; Communication effectiveness; Conflict resolution.
Given a map represented as a grid and a starting point, find the shortest path for a vehicle to reach a destination, considering dynamic obstacles that appear and disappear at specific grid cells and times. You can move horizontally, vertically, or stay put.
A strong answer shows: Graph traversal algorithms (BFS/Dijkstra); State space representation; Handling dynamic constraints; Pathfinding in 3D space (x, y, time).
