    Round 1

    Recruiter Screen
    Motivation, role fit, logistics.
  2. 2

    Round 2

    Coding Screen
    LeetCode-medium algorithmic problems under time pressure.
  3. 3

    Round 3

    System Design
    Distributed systems, trade-offs at scale, architecture under constraints.
  4. 4

    Round 4

    Onsite Coding
    LeetCode-hard problems, reasoning about defects, code clarity, edge cases.
  5. 5

    Round 5

    Behavioral / Leadership
    Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

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

  • Not considering bookings that span across month boundaries.
  • Introducing new bugs or complexity during refactoring.
  • Suggesting vertical scaling (bigger servers) as the primary solution without addressing horizontal scaling.
  • Not considering the order of operations when applying discounts (e.g., percentage off before or after taxes).

Test Yourself: Real Lodgify Questions

Three real prompts pulled from our database.

Type · learning

Lodgify integrates with many third-party OTAs like Airbnb and Booking.com, each with their own evolving APIs. Describe a time you had to adapt your system to a significant, breaking change in an external dependency. What was your process for ensuring the integration remained reliable during the transition?

Type · debugging

Here is a snippet of code intended to calculate the total revenue from bookings for a given month. It appears to have a bug. Please identify the bug, explain why it's happening, and provide the corrected code. ```python def calculate_monthly_revenue(bookings, month): total_revenue = 0 for booking in bookings: if booking['start_date'].month == month: total_revenue += booking['price'] return total_revenue ```

Type · algorithmic

Implement a function to check if a given string containing only '(', ')', '{', '}', '[' and ']' is valid. A string is valid if: 1. Open brackets must be closed by the same type of brackets. 2. Open brackets must be closed in the correct order. 3. Every close bracket has a corresponding open bracket of the same type.

Frequently asked questions

How long does the Lodgify 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 Lodgify?

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 Lodgify?

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.
