The Galapagos DNA (TL;DR)
The Galapagos 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 Galapagos interview outcomes, avoid these common traps:
- Not handling the cumulative aspect correctly or efficiently.
- Inefficient string searching or pattern matching algorithms (e.g., naive O(n*m)).
- Lack of a clear strategy for data versioning and lineage.
- Returning more or fewer than K genes without justification.

9 of 16 questions shown
Recruiter Screen
1- 1
Type · motivation
Galapagos is focused on developing innovative medicines for severe diseases. What specifically about our mission and therapeutic areas (e.g., inflammation, fibrosis, osteoarthritis, oncology) resonates with your career goals and technical interests as a software engineer?
Coding Screen
3- 2
Type · algorithmic
Given a dataset of patient genomic sequences and their corresponding drug responses, design an algorithm to efficiently find all sequences that exhibit a specific mutation pattern associated with a positive response to a novel drug candidate. Assume sequences can be very long and the dataset is large. - 3
Type · algorithmic
You are building a system to track the efficacy of different drug compounds over time in clinical trials. Design a data structure to store and query the cumulative effect of a drug on a patient cohort, considering that effects can be positive, negative, or neutral, and may vary in intensity. The queries should be efficient for finding trends and outliers. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · system-design
Design a system to manage and analyze large-scale genomic data for drug discovery. Consider data ingestion, storage, querying, and integration with existing bioinformatics tools. How would you ensure data integrity, security, and scalability? - 5
Type · system-design
Design a real-time monitoring system for a network of sensors in a pharmaceutical manufacturing facility. The system needs to collect data on temperature, humidity, and pressure, detect anomalies, and trigger alerts. Discuss scalability, fault tolerance, and data visualization. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
4- 6
Type · debugging
Here is a Python script that attempts to calculate the binding affinity of drug molecules to target proteins based on a simplified scoring function. It's producing incorrect results for some known cases. Debug and fix the script, ensuring it handles edge cases and is well-documented. - 7
Type · algorithmic
You are given two sets of gene expression profiles, one from healthy cells and one from cells treated with a potential drug. Design an algorithm to find the 'most significant' genes that are differentially expressed between the two sets, considering statistical significance and fold change. Return the top K genes. - + 2 more questions in this round (sign up to unlock)
Behavioral / Leadership
5- 8
Type · behavioral
Describe a time you encountered a significant technical challenge in a project, perhaps related to data integration or performance optimization for a complex biological dataset. How did you approach the problem, what was the outcome, and what did you learn from the experience? - 9
Type · behavioral
Tell me about a time you had a disagreement with a colleague or stakeholder regarding a technical decision or project direction. How did you handle the situation, and what was the resolution? - + 3 more questions in this round (sign up to unlock)
