The Polarsteps 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 problems, reasoning about defects, 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 Polarsteps interview outcomes, avoid these common traps:

Incorrectly defining or calculating the time threshold between locations.
Not specifying clear request/response formats (e.g., JSON, multipart/form-data for files).
Ignoring the impact on battery life or data usage for travelers
Incorrectly implementing the distance calculation (e.g., using Euclidean distance on lat/lon without considering Earth's curvature).

Test Yourself: Real Polarsteps Questions

Three real prompts pulled from our database.

Type · Data Structures

Imagine Polarsteps wants to implement a 'nearby friends' feature. Given a list of users with their current GPS coordinates and a target user's coordinates, efficiently find all users within a specified radius. Assume coordinates are (latitude, longitude).

Type · Debugging

A user reports that their trip map on Polarsteps is showing incorrect locations or is missing significant parts of their journey. Here's a simplified version of the data processing code. Identify potential bugs and suggest fixes.

Type · Motivation

What interests you about Polarsteps specifically, and how do you see your skills as a software engineer contributing to our mission of making travel planning and sharing seamless?

Recruiter Screen

1
Type · Motivation
What interests you about Polarsteps specifically, and how do you see your skills as a software engineer contributing to our mission of making travel planning and sharing seamless?

Coding Screen

2
Type · Algorithmic
Given a list of user travel itineraries, where each itinerary is a sequence of locations and timestamps, write a function to find the longest continuous travel segment for a given user. A continuous segment is defined by consecutive locations visited within a certain time threshold (e.g., 24 hours between leaving one location and arriving at the next).

System Design

4
Type · System Design
Design a system for Polarsteps that can process and display millions of user travel photos, including features like tagging, searching by location/date, and potentially generating personalized travel summaries based on photo content and metadata. Discuss scalability, storage, and retrieval.
5
Type · System Design
How would you design a real-time notification system for Polarsteps to alert users about new comments on their trip, friends nearby, or significant travel milestones? Consider delivery mechanisms, scalability, and potential for message queuing.

Onsite Coding

6
Type · Algorithmic
Implement a function that takes a user's travel history (a list of timestamped location visits) and returns a list of potential 'layover' locations. A layover is defined as a stop between two major travel segments (e.g., flights, long train rides) where the duration is significant enough to be considered a stopover but not a destination in itself (e.g., 6-48 hours).
7
Type · Debugging
A user reports that their trip map on Polarsteps is showing incorrect locations or is missing significant parts of their journey. Here's a simplified version of the data processing code. Identify potential bugs and suggest fixes.

Behavioral / Leadership

8
Type · Conflict Resolution
We often debate whether to prioritize offline-first data synchronization for remote travel locations versus optimizing for real-time social feed updates. Tell me about a time you advocated for a specific technical architectural direction when the team was split on the trade-offs. How did you ensure the final decision aligned with our user experience goals?
9
Type · Ownership
Our app relies heavily on accurate background location tracking, which is notoriously difficult due to varying OS power-saving policies. Describe a time you identified a recurring edge case in our location pipeline that was causing gaps in user trip maps. What was your process for investigating the root cause and implementing a more robust solution?

Frequently asked questions

How long does the Polarsteps 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 Polarsteps?

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 Polarsteps?

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.
