Affinity Global (IL) Software Engineer interview questions & guide 2026

Our interview process is designed to evaluate your technical depth and your ability to apply core engineering principles to real-world scenarios. While questions vary by team, the following patterns reflect the core technical competencies we look for in our Software Engineers.

Technical & Core Programming Concepts

These questions assess your foundational knowledge of programming languages and object-oriented principles, ensuring you have the building blocks necessary for complex development.

• Can you explain core OOPS concepts?
• How would you describe your previous project experience?

Preparation is essential to navigating our technical rigor. Focus your efforts on deep-diving into your past project work and reinforcing your mastery of core computer science concepts.

Role-Related Technical Knowledge – We expect you to be an expert in your primary stack. You should be prepared to discuss not just the "how" of your code, but the "why," especially concerning architectural choices and framework usage.

Database Mastery – Because our products rely heavily on data, you will be evaluated on your ability to optimize queries and design robust schemas. Ensure you are comfortable with advanced SQL concepts and performance tuning.

Experience & Project Depth – Your resume is the starting point for most technical deep dives. Be ready to walk through your previous projects in detail, explaining the challenges you faced and the specific technical decisions you made to overcome them.

The interview process at Affinity Global (IL) is designed to be thorough, ensuring that candidates possess both the technical capability and the problem-solving mindset required for our engineering team. You should expect a sequence that begins with an initial screening and progresses into rigorous technical assessments. These sessions often involve senior leadership, including VPs of product, which highlights the importance we place on technical alignment with our business goals.

The timeline above illustrates the progression from initial aptitude assessment to deep-dive technical interviews. Candidates should interpret these stages as an opportunity to demonstrate both breadth of knowledge and depth of expertise. Pace your preparation to handle multiple technical rounds, as the process is designed to test your consistency and ability to perform under pressure.

Database and Backend Architecture

We prioritize candidates who can demonstrate mastery over data persistence layers. You will be evaluated on your ability to design schemas that are not only functional but also scalable and performant.

Be ready to go over:

• SQL Optimization – Understanding how to write efficient queries and manage indexes.
• Data Modeling – Choosing the right relationships and structures for complex datasets.

As a Software Engineer, you will be responsible for the full lifecycle of feature development, from requirement analysis to deployment and maintenance. You will work closely with product managers and other engineers to translate business needs into technical specifications. A significant portion of your time will be spent writing high-quality, maintainable code and optimizing database interactions to ensure our platforms remain responsive under high load.

Collaboration is a pillar of our work. You will frequently interact with cross-functional teams to integrate new features into our existing ecosystem. Whether you are refining a MySQL database architecture or building new capabilities for CTV products, you are expected to take ownership of your code, participate in design reviews, and contribute to the ongoing improvement of our development standards.

A competitive candidate for this role possesses a blend of strong technical fundamentals and a pragmatic approach to software development. We look for engineers who are not just coders but system thinkers.

• Must-have skills: Proficient in SQL and relational database design, deep experience with backend programming (such as PHP/Laravel), and a solid understanding of Object-Oriented Programming (OOP).
• Nice-to-have skills: Experience in high-scale data environments, knowledge of CTV (Connected TV) advertising ecosystems, and exposure to cloud-native infrastructure.

Q: How long does the interview process typically take? The timeline can vary based on team availability, but we aim to move candidates through the stages efficiently. Expect the process to involve several technical rounds, which may span a few weeks.

Q: What is the most important factor in a successful interview? Successful candidates are those who can demonstrate a deep understanding of their past work. Being able to articulate the "why" behind your technical decisions is more important than memorizing definitions.

Q: Will I be interviewed by leadership? Yes, it is common for our senior leadership, including VPs of product, to participate in the interview process to ensure that technical hires are well-aligned with our long-term product strategy.

Q: How difficult are the technical interviews? The difficulty is geared toward testing your practical application of skills. Expect technical questions to be challenging and directly related to the work you will be doing, such as database optimization and architecture design.

• Own your projects: If it is on your resume, you should be prepared to explain it in depth. Be ready to discuss the specific architecture and the SQL queries you utilized.
• Be clear about your role: In team projects, clearly articulate your specific contributions versus the contributions of the team.
• Ask meaningful questions: Use the time with the VP or senior engineers to ask about the company’s technical challenges and long-term engineering roadmap.
• Stay calm under pressure: Some of our questions are designed to be tricky. If you don't know an answer immediately, walk the interviewer through your thought process.

The Software Engineer position at Affinity Global (IL) is a unique opportunity to work on high-impact, global-scale systems. By focusing on your core technical strengths, demonstrating deep knowledge of your past projects, and showing a collaborative mindset, you will be well-positioned to succeed in our rigorous evaluation process. Preparation is key; ensure you review your database fundamentals and be ready to discuss your technical decision-making in detail.
