How to Pass the Yazen Software Engineer Interview in 2026
The Yazen DNA (TL;DR)
Yazen Health's hiring emphasizes a candidate's ability to drive tangible outcomes in a regulated environment, particularly how they'd contribute to scaling the Yazen program. Interviewers, often including Elin Skoglund or Christina Waller Sterner, look for clear examples of navigating complex medical or product challenges.
The Yazen 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 Yazen interview outcomes, avoid these common traps:
- Lacking data or a clear business case to support the customer's request.
- Vague or missing impact/results.
- Not clearly articulating the steps taken in the debugging process.
- Inefficient iteration or repeated calculations.
Test Yourself: Real Yazen Questions
Three real prompts pulled from our database.
Type · Algorithmic
Implement a function that takes a list of patient IDs and their corresponding medication schedules (e.g., {'patient_id': 'med_id', 'time': 'HH:MM'}). The function should return a list of potential drug interaction alerts, flagging pairs of medications that are scheduled within 2 hours of each other for the same patient. Assume schedules are sorted by time.
Type · Ownership
Tell me about a time you took initiative to solve a problem that wasn't explicitly part of your job description. What was the situation, what did you do, and what was the outcome?

1
Recruiter Screen
1- 1
Type · Motivation
Why are you interested in joining Yazen, a company focused on the pharmaceutical industry, as a software engineer?
2
Coding Screen
3- 2
Type · Algorithmic
Given a dataset of patient treatment adherence over time, write a function to identify patients who have shown a consistent decline in adherence by more than 15% week-over-week for at least three consecutive weeks. Assume adherence is represented as a percentage. - 3
Type · Algorithmic
You have a stream of drug prescription events, each with a timestamp and a drug ID. Design an algorithm to efficiently count the number of unique drugs prescribed within any given rolling 24-hour window. The system should handle a high volume of events. - + 1 more questions in this round (sign up to unlock)
3
System Design
3- 4
Type · System Design
Design a system to monitor and alert healthcare providers in real-time about potential adverse drug reactions (ADRs) based on patient-reported symptoms and medication history. Consider data sources, processing, and alerting mechanisms. - 5
Type · System Design
How would you design a distributed system to manage and serve personalized drug information and dosage reminders to millions of patients globally? Consider aspects like data consistency, latency, and reliability. - + 1 more questions in this round (sign up to unlock)
4
Onsite Coding
3- 6
Type · Algorithmic
You are given a list of clinical trial results, each with a start date, end date, and a list of reported side effects. Write a function to find the drug that had the highest incidence of a specific side effect within a given time frame. Handle overlapping trial periods. - 7
Type · Debugging
A critical patient monitoring service is intermittently failing to send alerts. The logs show occasional 'database connection timeout' errors, but the database itself appears healthy and responsive to other queries. Debug this issue. - + 1 more questions in this round (sign up to unlock)
