How to Pass the Vay Software Engineer Interview in 2026

The Vay DNA (TL;DR)

Vay's 'Building the Future of Mobility' vision drives its hiring, seeking individuals who can articulate complex technical solutions for novel challenges in remote driving. The interview process often includes deep dives into hypothetical scenarios related to their teleoperated vehicle systems.

The Vay Interview Loop

Your onsite loop will typically consist of 5 rounds.

  1. 1

    Round 1

    Recruiter Screen
    Motivation, role fit, logistics.
  2. 2

    Round 2

    Coding Screen
    LeetCode-medium algorithmic problems under time pressure.
  3. 3

    Round 3

    System Design
    Distributed systems, trade-offs at scale, architecture under constraints.
  4. 4

    Round 4

    Onsite Coding
    LeetCode-hard, debugging, code clarity, edge cases.
  5. 5

    Round 5

    Behavioral / Leadership
    Past 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.

Test Yourself: Real Vay Questions

Three real prompts pulled from our database.

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?

Type · Algorithmic

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.

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. 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.
  2. 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. 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.
  2. 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. 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.
  2. 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.
