How to Pass the Skello Software Engineer Interview in 2026
The Skello DNA (TL;DR)
Skello's interviewers assess how candidates would enhance the 'Pointeuse Gestion' and scheduling features, looking for clear examples of driving efficiency in complex environments like Grande Distribution. They seek individuals who can articulate the impact of their work on operational metrics.
The Skello Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Skello interview outcomes, avoid these common traps:
- Lack of indexing strategies, leading to slow query performance.
- Not achieving the desired outcome or not learning from the experience.
- Describing a situation without detailing their own actions or thought process.
- Showing a lack of genuine curiosity or effort to learn.
Test Yourself: Real Skello Questions
Three real prompts pulled from our database.
Type · Database Design
Skello needs to store and efficiently query employee time tracking data. Propose a database schema (or schemas) to handle this, considering potential growth in data volume and the need for various reporting queries (daily hours, weekly summaries, overtime calculations).
Type · String Manipulation
Employee names in the system might have inconsistent formatting (e.g., 'john doe', 'Doe, John', 'JOHN A. DOE'). Write a function to normalize these names to a consistent 'FirstName LastName' format.

A user reports that their calculated weekly hours are incorrect, showing fewer hours than expected. Here's a snippet of the relevant code. Identify the bug, explain why it occurs, and provide a corrected version. - 7
Type · Algorithm - Hard
Implement a feature for Skello that detects potential 'time theft' or 'buddy punching' by identifying employees whose clock-in/out patterns are highly suspicious (e.g., identical times for multiple employees, unusually short/long breaks). Define your criteria for 'suspicious' and implement the detection logic. - + 1 more questions in this round (sign up to unlock)
