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 Flok Health interview outcomes, avoid these common traps:
- Claiming to learn something without specific examples or demonstrable results.
- Not planning for offline data synchronization or handling intermittent connectivity.
- Inefficiently iterating through the data, leading to O(n^2) complexity.
- Making assumptions about the data without verifying.

9 of 16 questions shown
Recruiter Screen
1- 1
Type · motivation
What interests you about Flok Health's mission in the pharmaceutical space, and how do you see your software engineering skills contributing to our goal of improving patient outcomes?
Coding Screen
3- 2
Type · algorithmic
Given a dataset of patient treatment adherence over time (represented as a list of timestamps for each patient), write a function to identify patients who have adhered to their treatment schedule with a deviation of no more than X days between consecutive prescribed doses. Assume the prescribed interval is constant. - 3
Type · algorithmic
Design a data structure that can efficiently store and retrieve patient medication history, supporting operations like adding a new prescription, retrieving all prescriptions for a given patient, and finding the most recent prescription for a specific drug. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · architecture
Design a system to monitor and alert healthcare providers in real-time about potential adverse drug reactions (ADRs) based on patient-reported symptoms and electronic health records (EHRs). Consider data ingestion, processing, and alerting mechanisms. - 5
Type · architecture
How would you design a scalable API for a pharmaceutical company that serves personalized drug information and dosage recommendations to patients based on their medical history, demographics, and genetic data? Discuss data storage, caching, and request handling. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
4- 6
Type · algorithmic
Implement a function to calculate the 'adherence score' for a patient based on their medication intake logs. The score should penalize missed doses, late doses, and early doses, with configurable weights for each type of deviation. Consider edge cases like irregular prescription changes. - 7
Type · algorithmic
Given a stream of anonymized patient health events (e.g., doctor visits, prescription fills, symptom reports), design an algorithm to detect anomalous patterns that might indicate a potential public health issue or a rare side effect. You can assume a baseline of 'normal' behavior. - + 2 more questions in this round (sign up to unlock)
Behavioral / Leadership
5- 8
Type · ownership
Tell me about a time you encountered a significant technical challenge or bug in a production system that had a direct impact on users. What steps did you take to diagnose, resolve, and prevent recurrence? - 9
Type · collaboration
Describe a situation where you had a technical disagreement with a colleague or team lead regarding an architectural decision or implementation detail. How did you approach the discussion, and what was the outcome? - + 3 more questions in this round (sign up to unlock)
