DONNELLY & MOORE Full Stack Engineer interview questions & guide 2026

Our interview process is designed to evaluate your depth of knowledge across the full stack. The questions below represent the patterns we look for in successful candidates, focusing on your ability to articulate technical decisions and solve problems under pressure.

Technical Proficiency and Frameworks

These questions assess your foundational knowledge of the specific languages and frameworks required for our stack, such as .NET and Angular.

• Describe the lifecycle of a component in Angular.
• How do you handle dependency injection in .NET applications?

Preparation for a Full Stack Engineer role at DONNELLY & MOORE requires a balanced approach. You should be prepared to discuss both the "how" (implementation details) and the "why" (architectural trade-offs) of your technical choices.

Role-related knowledge – We evaluate your proficiency with our core tech stack, particularly .NET and Angular. You should be prepared to dive deep into language-specific features, common design patterns, and framework-level best practices.

Problem-solving ability – We are interested in your structured approach to complex challenges. When presented with a problem, explain your thought process clearly, identify potential constraints, and articulate the trade-offs of your proposed solution.

Communication and Collaboration – As a member of a broader team, your ability to explain technical concepts to diverse stakeholders is vital. Be ready to discuss how you have worked within a team to overcome obstacles or deliver features on time.

The interview process at DONNELLY & MOORE is structured to be thorough yet efficient, ensuring we identify candidates who possess the right blend of technical expertise and cultural alignment. You can expect a progression that starts with an initial screening to gauge your background and interest, followed by deeper technical assessments that test your hands-on coding ability and architectural thinking.

We prioritize a collaborative environment, so expect your interviewers to engage with you in a dialogue rather than a one-way interrogation. Our process is designed to simulate real-world scenarios, giving you a glimpse into the challenges our team faces daily. We value clarity, precision, and a proactive mindset throughout every stage.

The visual timeline above illustrates the typical stages you will navigate, from initial screens to final technical evaluations. Use this to pace your preparation, ensuring you have enough time to review both your foundational coding skills and your high-level architectural knowledge before the later stages.

Technical Depth

We look for candidates who understand the underlying mechanics of the technologies they use. Being able to explain the "why" behind a specific framework choice or coding pattern is what separates good engineers from great ones.

Be ready to go over:

• .NET Ecosystem – Mastery of C# and the .NET framework is essential.
• Front-end Frameworks – Expertise in Angular and its integration with back-end services.

As a Full Stack Engineer, your daily work will revolve around the full lifecycle of application development. You will spend your time writing clean, efficient code for both client-side and server-side components. This involves building interactive user interfaces, designing robust API endpoints, and ensuring seamless communication between the two.

Collaboration is a cornerstone of this role. You will work closely with product managers to refine requirements and with other engineers to conduct code reviews and architectural discussions. You are expected to be an active participant in our agile ceremonies, contributing to sprint planning and helping to identify potential technical risks early in the development cycle.

Beyond feature development, you will also be responsible for maintaining existing codebases. This includes troubleshooting production issues, optimizing performance, and upgrading dependencies to keep our systems secure and up to date. Your ability to balance new feature delivery with long-term system health is critical to the team's success.

A strong candidate for the Full Stack Engineer position will demonstrate a blend of technical depth, experience, and a collaborative spirit. We prioritize candidates who can hit the ground running with our existing stack while also bringing fresh perspectives to our development processes.

• Must-have skills – Proficient knowledge of .NET and Angular, strong understanding of RESTful API design, and a solid grasp of relational database concepts.
• Experience level – We look for candidates who have a proven track record of delivering end-to-end features in a professional team setting.
• Soft skills – Strong verbal and written communication skills, the ability to mentor junior developers, and a proactive approach to problem-solving.
