The AUTO1 Group 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 AUTO1 Group interview outcomes, avoid these common traps:
- Avoiding conflict or giving in too easily without advocating for their technical opinion.
- Not reflecting on the impact on the relationship or future collaboration.
- Focusing on syntax errors while missing logical flaws.
- Implementing a single depreciation method without considering extensibility for others.

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)
System Design
3- 4
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)

Sample answers
What a strong answer to these AUTO1 Group interview questions shows.
Design a system to detect duplicate car listings based on a combination of attributes (e.g., VIN, engine serial number, or a fuzzy match on other details).
A strong answer shows: Use of hashing or other efficient comparison techniques.; Strategies for handling missing or inconsistent data.; Discussion of trade-offs between precision and recall..
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).
A strong answer shows: Recognition of the TSP nature of the problem.; Discussion of approximation algorithms or heuristics if exact solutions are too slow.; Clean implementation with good variable naming and structure.; Handling of edge cases and potential errors..
