How to Pass the Endesa Software Engineer Interview in 2026

The Endesa DNA (TL;DR)

The final behavioral round often probes how candidates would improve the 'Endesa Clientes' experience. Interviewers look for demonstrated ability to manage complex energy projects, ensure grid reliability, and identify efficiencies that directly impact service delivery, often through specific project examples.

The Endesa Interview Loop

Your onsite loop will typically consist of 4 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 Endesa interview outcomes, avoid these common traps:

Overlooking the complexity of real-time price fluctuations and grid constraints.
Ignoring the impact of special events or weather on demand.
Incorrectly handling edge cases like no readings above the threshold, or readings that start/end exactly at the threshold.
Not designing for concurrent charging requests and potential conflicts.

Test Yourself: Real Endesa Questions

Three real prompts pulled from our database.

Type · algorithmic

Design and implement a data structure that can efficiently store and query historical energy generation data from multiple renewable sources (solar, wind, hydro). The queries should support finding the total generation within a given time range and identifying the source that contributed the most generation during that period.

Type · design

Design a distributed system for managing and optimizing charging schedules for a fleet of electric vehicles (EVs) for commercial use. The system should consider electricity prices, grid load, and vehicle availability.

Type · debugging

A customer reports that their smart thermostat is not correctly adjusting heating based on the predicted occupancy schedule, leading to wasted energy. Here is a simplified code snippet for the thermostat's logic. Debug and fix the issue.

Recruiter Screen

1
Type · motivation
What interests you about working at Endesa, specifically within the energy sector, and how do you see your skills contributing to our mission of driving the energy transition?

Coding Screen

2
Type · algorithmic
Given a list of energy consumption readings from smart meters over a day, write a function to identify and return the time intervals (start and end times) where the consumption exceeded a certain threshold, considering consecutive readings that meet the criteria.
3
Type · algorithmic
You are given a dataset representing energy grid load and renewable energy generation (solar, wind) for different regions. Design an algorithm to find the region with the highest net energy surplus (generation - load) for a given hour, and if there's a tie, prioritize the region with the most diverse renewable sources.

System Design

4
Type · design
Design a system to monitor and alert on real-time energy grid stability issues. Consider factors like voltage fluctuations, frequency deviations, and potential overload conditions across a large geographical area.
5
Type · design
Design a distributed system for managing and optimizing charging schedules for a fleet of electric vehicles (EVs) for commercial use. The system should consider electricity prices, grid load, and vehicle availability.

6
Type · debugging
A customer reports that their smart thermostat is not correctly adjusting heating based on the predicted occupancy schedule, leading to wasted energy. Here is a simplified code snippet for the thermostat's logic. Debug and fix the issue.
7
Type · algorithmic
You are building a system to forecast energy demand for a city. Given historical demand data, weather forecasts, and a calendar of special events (e.g., holidays, major sports games), write a function to predict the energy demand for the next 24 hours. Assume you have access to helper functions for parsing weather data and event impact.

Behavioral / Leadership

8
Type · ownership
Tell me about a time you encountered a significant technical challenge in a project that was critical for the business. How did you take ownership of the problem, what steps did you take to resolve it, and what was the outcome?
9
Type · conflict_resolution
In the context of the Endesa Clientes platform, describe a time when you had to reconcile conflicting requirements between the energy grid operations team wanting to limit real-time data polling to ensure stability and the digital product team wanting more frequent customer usage updates. How did you negotiate this trade-off to ensure a seamless user experience without compromising system reliability?
