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 problems, reasoning about defects, 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 AUTO1 Group interview outcomes, avoid these common traps:
- Proposing a brute-force solution that doesn't scale for large datasets.
- Implementing a naive brute-force solution for TSP without acknowledging its complexity.
- Not considering distributed systems and how to maintain state across multiple servers.
- Failing to handle division by zero or invalid input values.

3- 2
Type · Algorithmic
Given a dataset of car listings with features like price, mileage, and age, design an algorithm to efficiently find the N most relevant listings for a user's specific search criteria (e.g., budget, max mileage, preferred age range). - 3
Type · Algorithmic
Implement a function to calculate the depreciation of a car over time, considering initial price, salvage value, and a chosen depreciation method (e.g., straight-line, declining balance). Handle potential edge cases like zero initial price or negative salvage value. - + 1 more questions in this round (sign up to unlock)

Type · System Design
Design a real-time pricing engine for used cars. Users should be able to input car details and receive an estimated price instantly. Consider factors like market demand, seasonality, car condition, and historical sales data. - 5
Type · System Design
Design a notification system for car buyers and sellers. Buyers should receive alerts for new listings matching their criteria, price drops, or offers. Sellers should be notified of new inquiries or offers on their cars. - + 1 more questions in this round (sign up to unlock)

Type · Coding
Implement a function to calculate the optimal route for a car inspection agent visiting multiple dealerships in a city. Assume you are given the locations of dealerships and the agent's starting point. This is a variation of the Traveling Salesperson Problem (TSP). - 7
Type · Coding
Implement a rate limiter for API requests to prevent abuse. The limiter should allow a certain number of requests per user per time window (e.g., 100 requests per minute).

Behavioral / Leadership
3- 8
Type · Behavioral
Tell me about a time you had to work with a legacy codebase that was difficult to understand or modify. How did you approach the task, and what was the outcome? - 9
Type · Behavioral
At AUTO1, we often balance the need for rapid feature deployment on our dealer-facing platform against the technical debt inherent in scaling a legacy inventory management system. Describe a time you prioritized a high-impact technical refactor that initially met resistance from business stakeholders focused on short-term delivery. How did you communicate the long-term operational cost of the current architecture and align the team on the necessary trade-offs? - + 1 more questions in this round (sign up to unlock)

Frequently asked questions
How long does the AUTO1 Group interview process take?
Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.
How should I prepare specifically for AUTO1 Group?
Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.
Does this apply to engineering or design roles at AUTO1 Group?
The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.
