How long does the TravelPerk 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 TravelPerk?

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 TravelPerk?

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.

Why are you interested in working at TravelPerk, and what specifically about our mission or product excites you as a software engineer?

Type: Motivation. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Given a list of flight bookings, each with a departure and arrival city and time, find the shortest layover time between any two consecutive flights for a given traveler. Assume flights are always in chronological order for a single traveler.

Type: Algorithmic. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Implement a function to determine if a given string representing a user's search query for flights is valid. A valid query must contain at least a departure and arrival city, and optionally a date. Cities should be at least 3 characters long.

Type: Algorithmic. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Design a system to suggest optimal flight routes to users based on their preferences (e.g., shortest duration, fewest stops, lowest price) and real-time flight data. Consider how to handle updates to flight schedules and pricing.

Type: System Design. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Design a notification service for TravelPerk that alerts users about flight changes (delays, cancellations, gate changes). How would you ensure timely and reliable delivery of these notifications?

Type: System Design. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Here is a Python function that calculates the total cost of a trip, including flights and hotels. It's producing incorrect results for certain inputs. Find the bug and fix it. [Provide a code snippet with a subtle bug, e.g., incorrect float comparison, off-by-one error in a loop, or mishandling of optional fields].

Type: Debugging. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Implement a function to find the cheapest flight path between two cities, given a list of available flights with their prices and layovers. You can take multiple flights. This is similar to Dijkstra's algorithm but with a focus on cost.

Type: Algorithmic. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Tell me about a time you had a significant disagreement with an engineer or designer about a product decision. How did you approach it, and what was the outcome?

Type: Conflict Resolution. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Tell me about a time you took initiative to solve a problem that wasn't explicitly assigned to you. What was the situation, and what was the result?

Type: Ownership. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

How to Pass the TravelPerk Software Engineer Interview in 2026

The TravelPerk DNA (TL;DR)

TravelPerk values candidates who demonstrate strong problem-solving skills, customer obsession, and adaptability in a fast-paced, global environment. They look for collaborative individuals who align with their mission to simplify business travel.

The TravelPerk 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 TravelPerk interview outcomes, avoid these common traps:

Not designing for high availability and fault tolerance.
Not reflecting on the outcome or lessons learned.
Not taking ownership of their role in the conflict.
Presenting the disagreement as a personal conflict rather than a technical debate.

Test Yourself: Real TravelPerk Questions

Three real prompts pulled from our database.

Type · Conflict Resolution

Tell me about a time you had a significant disagreement with a colleague or manager. How did you handle it, and what was the resolution?

Type · Algorithmic

You are given a list of company travel policies, each with a maximum budget for flights, hotels, and car rentals. Write a function to check if a proposed trip itinerary exceeds any of these policy limits.

Type · System Design

Design a system to detect and flag potentially fraudulent bookings. Consider the types of data you would use and how you would process it to identify suspicious patterns.
