How to Pass the Rohlik Software Engineer Interview in 2026

The Rohlik DNA (TL;DR)

Rohlik seeks individuals who can drive tangible impact in a high-growth environment, particularly those who demonstrate a keen understanding of operational efficiency in areas like last-mile delivery optimization. They look for candidates who can quickly adapt and contribute to scaling their platform, often evidenced by specific examples of streamlining workflows or improving delivery metrics.

The Rohlik Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, role fit, logistics.
2
Round 2
Coding Screen
LeetCode-medium algorithmic problems under time pressure.
3
Round 3
System Design
Distributed systems, trade-offs at scale, architecture under constraints.
4
Round 4
Onsite Coding
LeetCode-hard, debugging, code clarity, edge cases.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Rohlik interview outcomes, avoid these common traps:

Claiming to learn things instantly without any struggle.
Not identifying potential bottlenecks (e.g., database, message queues, specific services).
Focusing only on the negative aspects without highlighting learning or positive outcomes.
Focusing on the problem without detailing their specific actions and the outcome.

Test Yourself: Real Rohlik Questions

Three real prompts pulled from our database.

Type · algorithmic

Given a list of delivery orders with pickup and dropoff locations (latitude, longitude) and estimated delivery times, design an algorithm to find the optimal route for a single driver to complete all orders within their time windows, minimizing total travel time. Assume a simplified map model.

Type · conflict resolution

Tell me about a time you had a significant disagreement with a colleague or manager regarding a technical decision. How did you approach the situation, and what was the outcome?

Type · Influence

Describe a situation where you had to influence a stakeholder or team who initially disagreed with your recommendation. How did you approach it, and what was the result?

Recruiter Screen

1
Type · motivation
What interests you about working at Rohlik, specifically within our engineering team focused on optimizing grocery delivery logistics?

Coding Screen

2
Type · algorithmic
Given a list of delivery orders with pickup and dropoff locations (latitude, longitude) and estimated delivery times, design an algorithm to find the optimal route for a single driver to complete all orders within their time windows, minimizing total travel time. Assume a simplified map model.
3
Type · data structures
We need to efficiently track the real-time location of thousands of delivery drivers and query for drivers within a certain geographical radius of a customer's pickup location. What data structures would you use to optimize these queries?

System Design

4
Type · api design
Design the API for a service that manages driver assignments to delivery orders. Consider endpoints for assigning orders, updating order status, and retrieving driver availability. Discuss authentication, rate limiting, and potential failure scenarios.
5
Type · scalability
Rohlik's delivery volume is growing rapidly. How would you design a system to handle a 10x increase in concurrent orders and driver updates, ensuring low latency for both customers and drivers?

Onsite Coding

6
Type · debugging
A customer reports that their order was marked as delivered, but they never received it. The system logs show the driver's GPS pinged as 'delivered' at the correct address. Walk me through how you would debug this issue, considering potential causes from the driver app, backend services, and data integrity.
7
Type · code quality
Refactor the following code snippet (provide a small, intentionally suboptimal Python/Java/etc. function for calculating delivery time estimates based on distance and traffic) to improve its readability, maintainability, and testability. Discuss the trade-offs of your changes.

Behavioral / Leadership

8
Type · Conflict Resolution
Tell me about a time you had a significant disagreement with a cross-functional team member (e.g., engineer, marketer, operations manager) about a product decision. How did you approach it, and what was the outcome?
9
