How long does the Iberia 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 Iberia?

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 Iberia?

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.

The Iberia 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 Iberia interview outcomes, avoid these common traps:

Generic answers not tailored to Iberia or the travel industry.
Inefficient sorting or searching of flight data, leading to poor time complexity.
Assuming a direct flight is always available or optimal.
Failing to account for travel time between airports or security checks.

Test Yourself: Real Iberia Questions

Three real prompts pulled from our database.

Type · algorithmic

Implement a function that takes a list of flight segments (origin, destination, departure time, arrival time) and determines if a traveler can complete a given multi-city itinerary within the specified times. Return the minimum connection time required at each stop.

Type · motivation

Why are you interested in working at Iberia, specifically within our technology team, and what aspects of the travel industry excite you?

Type · conflict resolution

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

Coding Screen

2
Type · algorithmic
Given a list of flight bookings (each with a departure and arrival airport code and timestamp), write a function to find the longest layover duration for any given passenger's journey. Assume a passenger takes only one connecting flight.

System Design

4
Type · design
Design a system to recommend personalized travel packages (flights + hotels) to Iberia customers based on their past booking history, browsing behavior, and stated preferences. Consider scalability for millions of users and real-time updates.
5
Type · design
Design a real-time flight status notification system for Iberia. Users should receive immediate updates on delays, gate changes, and cancellations via push notifications and SMS. How would you handle millions of concurrent users and ensure low latency?

Onsite Coding

6
Type · algorithmic
Given a set of flight routes (origin, destination, price) and a starting airport, find the cheapest way to travel to a target destination, allowing for multiple layovers. You can take multiple flights. Return the minimum cost.
7
Type · debugging
The following code attempts to calculate the optimal seat allocation for a flight based on passenger preferences (e.g., window, aisle, exit row) and availability. It's failing to assign seats correctly in certain scenarios. Debug and refactor the code for clarity and correctness.

Type · past-experience
Tell me about a time you had to debug a particularly challenging production issue. What was the issue, how did you approach it, and what was the outcome?
9
Type · past-experience
Describe a situation where you had a significant disagreement with a colleague or manager about a technical decision. How did you handle it, and what was the resolution?
