How long does the Corti interview process take?

Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.

How should I prepare specifically for Corti?

Focus on three things: (1) the company DNA shown above — what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at Corti?

The DNA stays the same — what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.

How to Pass the Corti Software Engineer Interview in 2026

The Corti DNA (TL;DR)

Corti values candidates who demonstrate deep technical expertise in AI/ML, particularly in real-time audio processing for healthcare. They seek individuals with a strong understanding of clinical workflows, patient safety, and ethical AI deployment, emphasizing problem-solving and impactful contributions to patient outcomes.

The Corti Interview Loop

Your onsite loop will typically consist of 5 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 Corti interview outcomes, avoid these common traps:

Inefficiently processing the stream (e.g., loading all data into memory).
Not systematically testing different inputs or edge cases.
Making a decision based purely on gut feeling without any structured analysis.
Not clearly defining their specific role and contribution.

Test Yourself: Real Corti Questions

Three real prompts pulled from our database.

Type · Data Structures

Design a data structure to efficiently store and retrieve patient symptom data, allowing for quick lookups based on symptom combinations and temporal proximity (e.g., finding all patients who reported 'fever' within 24 hours of 'cough').

Type · Algorithm

Implement a function that takes a list of doctor's notes (strings) and returns a data structure summarizing the frequency of specific medical terms (e.g., 'hypertension', 'diabetes') mentioned across all notes. The function should be optimized for a large number of notes.

Type · Scalability

Corti's AI diagnostic tool is experiencing increased load. How would you design a system to handle a 10x increase in concurrent users while maintaining low latency for diagnostic suggestions?

9 of 22 questions shown

Recruiter Screen

1
Type · Motivation
What interests you about working as a Software Engineer at Corti, specifically within the pharmaceutical industry?

Coding Screen

2
Type · Algorithm
Given a dataset of patient interactions with a Corti-powered diagnostic tool, write a function to identify the top 3 most frequent diagnostic pathways that led to a specific outcome (e.g., 'referral to specialist'). Assume interactions are logged as a sequence of symptoms and questions.
3
Type · Algorithm
Implement a function that takes a list of doctor's notes (strings) and returns a data structure summarizing the frequency of specific medical terms (e.g., 'hypertension', 'diabetes') mentioned across all notes. The function should be optimized for a large number of notes.

System Design

4
Type · API Design
Design an API endpoint for Corti's platform that allows healthcare providers to securely upload patient diagnostic reports (e.g., PDFs, structured data) for analysis and summarization by our AI.
5
Type · Data Pipeline
Outline the design for a data pipeline that ingests anonymized patient interaction data from our diagnostic tools, processes it for quality, and stores it in a data warehouse for further analysis by our research teams.

Onsite Coding

6
Type · Algorithm
Given a stream of real-time patient vital signs (e.g., heart rate, blood pressure) and a set of predefined critical thresholds, implement a system that detects and alerts on any vital sign falling outside the acceptable range for a sustained period (e.g., 5 minutes).
7
Type · Data Structures
Design a data structure to efficiently store and retrieve patient symptom data, allowing for quick lookups based on symptom combinations and temporal proximity (e.g., finding all patients who reported 'fever' within 24 hours of 'cough').

Behavioral / Leadership

8
Type · Influence
Tell me about a time you had to influence a team or stakeholder who was resistant to your idea or direction.
9
Type · Dealing with Ambiguity
Tell me about a time you had to make a critical decision with incomplete information. How did you approach it, and what was the outcome?
