To excel in your interviews, you need to understand exactly how our engineering teams evaluate your skills. We focus on a blend of practical coding, theoretical knowledge, and behavioral alignment.
Core Data Structures and Algorithms
While we do not ask obscure, hyper-complex competitive programming questions, we do expect a rock-solid understanding of foundational computer science. This area is typically evaluated through an Online Assessment or a straightforward coding exercise during a video call. Strong performance means writing functional, readable code and clearly explaining your time and space complexity.
Be ready to go over:
- Arrays and Strings – Manipulating data, two-pointer techniques, and string parsing.
- Hash Maps and Sets – Using key-value stores for optimal lookups and data frequency counting.
- Linked Lists and Trees – Basic traversal, insertion, and deletion algorithms.
- Advanced concepts (less common) – Basic graph traversal (BFS/DFS) and simple dynamic programming scenarios.
Example questions or scenarios:
- "Given a string of text, write a function to find the most frequently occurring word, excluding a list of stop words."
- "Explain how you would reverse a linked list, and write the code to do so."
- "Walk us through how a hash map functions under the hood, including how it handles collisions."
Software Engineering Concepts and Architecture
During your technical panel interview, we will move beyond writing code to discuss how you build software. We want to know that you understand how different pieces of a system interact and how to write maintainable software. Strong candidates can discuss theoretical concepts and relate them directly to their past experiences.
Be ready to go over:
- Object-Oriented Programming (OOP) – Inheritance, encapsulation, polymorphism, and when to use them.
- API Design – RESTful principles, handling requests, and structuring JSON responses.
- Database Fundamentals – SQL vs. NoSQL, basic indexing, and understanding relational data.
- Advanced concepts (less common) – Microservices architecture, CI/CD pipelines, and cloud infrastructure basics.
Example questions or scenarios:
- "Describe the difference between an abstract class and an interface, and tell me when you would use each."
- "How would you design a simple REST API to serve research publications to a front-end application?"
- "Explain a time when you had to optimize a slow-performing database query."
Resume Deep Dive and Behavioral Fit
We place a heavy emphasis on who you are as a teammate. The American Enterprise Institute values positive energy, intellectual curiosity, and clear communication. Your interviewers will spend significant time walking through your CV to understand your actual contributions to past projects.
Be ready to go over:
- Project Ownership – What specific parts of a project you built versus what the team built.
- Conflict Resolution – How you handle disagreements on technical approaches or deal with shifting requirements.
- Adaptability – Your willingness to learn new tech stacks or dive into unfamiliar legacy code.
Example questions or scenarios:
- "Walk me through the most technically challenging project on your resume. What was your specific role?"
- "Tell me about a time you received critical feedback on a pull request. How did you handle it?"
- "Why are you interested in bringing your software engineering skills to a policy and research institute?"
