Code and Theory Software Engineer interview questions & guide 2026

The following questions represent patterns observed in Code and Theory interviews. While specific technical requirements vary by team and seniority, the core objective remains consistent: assessing your practical proficiency and your ability to articulate your technical decision-making process.

Technical & Domain Expertise

These questions test your mastery of specific languages, automation tools, and your ability to apply technology to practical business problems.

• How can you automate a file in Excel using Google Apps Script?
• Can you explain your experience with Selenium for test automation?

Preparation for Code and Theory requires a blend of rigorous technical practice and clear, concise communication. Do not assume that technical prowess alone is sufficient; you must be able to explain the "why" behind your technical choices.

Role-Related Knowledge – You should be prepared to demonstrate deep proficiency in the specific tech stack listed in your job description, such as Python, PHP, or Java. Interviewers will look for evidence that you can navigate both standard software development tasks and specialized automation requirements.

Problem-Solving Ability – You will be evaluated on your logical approach to complex or ambiguous technical challenges. Focus on how you structure your thoughts, how you test your assumptions, and how you iterate on a solution during a coding exercise.

Communication & Collaboration – As an agency, Code and Theory values professionals who can explain technical concepts to non-technical stakeholders. Be ready to discuss your past projects in terms of both their technical implementation and their business impact.

The interview process at Code and Theory is designed to be comprehensive yet efficient, reflecting the fast-paced nature of agency life. You can expect a structured journey that begins with a recruiter screen to establish baseline alignment, followed by a series of technical assessments, and culminating in interviews with engineering leadership.

The rigor of the process is intentional. The firm prioritizes candidates who show a blend of technical depth and the ability to work effectively across different departments. Depending on the role, you may encounter written exams, coding exercises (often via platforms like HackerRank), and behavioral discussions that probe how you navigate team dynamics and project constraints.

This timeline provides a high-level view of your progression from initial screening to final decision. Use this structure to pace your preparation, ensuring you have dedicated time for both technical brush-ups and behavioral storytelling. Note that while some processes are streamlined into a single day, others may span several weeks depending on team availability and project requirements.

Technical Proficiency

This is the bedrock of your interview. Expect to be tested not just on theoretical knowledge, but on your ability to apply code to real-world problems, such as automation or systems integration. Strong performance involves writing clean, maintainable code and being able to debug your own work under pressure.

Be ready to go over:

• Automation scripting – Using tools like Google Apps Script or Python to streamline operational tasks.
• Testing methodologies – Your experience with frameworks like Selenium and your philosophy on test-driven development.

As a Software Engineer, your daily life will involve designing and implementing features for client projects, maintaining existing codebases, and collaborating with cross-functional teams. You will often work on multiple workstreams, which requires excellent time management and the ability to context-switch without sacrificing code quality.

You will be expected to participate in code reviews, contribute to architectural discussions, and ensure that your technical solutions are scalable and secure. Collaboration is key; you will frequently interface with product managers to define requirements and with creative teams to ensure the technical implementation matches the intended user experience.

A competitive candidate for a Software Engineer position at Code and Theory brings a mix of foundational computer science knowledge and practical, project-based experience.

• Must-have skills – Proficiency in core languages like Python, PHP, or Java; experience with automation and scripting; a strong grasp of software engineering fundamentals.
• Nice-to-have skills – Experience in agency environments; familiarity with security and compliance protocols; experience with cloud-based infrastructure and modern CI/CD pipelines.
• Experience level – While requirements vary by role, a track record of delivering production-ready code in a team-based environment is essential.

Q: How long does the interview process typically take? The process can range from a few days to a few weeks depending on the role level and team urgency. Some candidates report a very efficient, one-day process, while others experience a more traditional multi-round schedule.

Q: What is the best way to prepare for the technical exam? Focus on practical application. Practice coding in a web-based IDE, brush up on your scripting skills, and ensure you are comfortable writing clean, efficient code for common automation tasks.

Q: Is the culture collaborative or competitive? Code and Theory is known for a highly collaborative environment. You will be expected to work closely with other disciplines, so emphasize your team-first mindset during behavioral interviews.

Q: Are there remote work opportunities? Expectations around location are typically addressed during the recruiter screen. Given the global nature of the company, many roles may offer flexibility, but always confirm the specific requirements for your target location.

• Understand the "Agency" Mindset: Projects move fast and client needs evolve. Show that you are comfortable with ambiguity and can deliver high-quality work in dynamic environments.
• Master Your Resume: Every line on your resume is fair game. Be prepared to go into deep detail about any project or technology you have listed.
• Ask Strategic Questions: At the end of your interviews, ask about the team’s current technical challenges or how they balance technical debt with new feature development.
• Practice Your "Why": Have a clear, compelling story about why you want to work at Code and Theory specifically, rather than just any engineering firm.
