Example interview questions for software architects
Prepare with the example interview questions and answers below to practice your responses so you're ready to make a great impression:
How do you decide between web applications and locally installed applications?
This question can help interviewers evaluate your ability to make important decisions based on client needs. Explain your methods for applying client specifications and deciding on the solutions that best meet the client's needs to highlight your communication and analytical skills.
Example: "Ultimately, my decision to use either structure depends on what the client wants to achieve with the application. In my last role, I first collaborated with clients to understand what objectives they needed their software to achieve. One client was a large-chain retailer that required a large-scale web application to support online shopping. My team and I consulted with the client to establish the main specifications for the application, and I used these parameters to decide on a web application to better support the client's business success."
How do you apply the SOLID principles to functional programming and deep-level system architecture?
The SOLID principles encompass important methodologies for designing software applications, and your ability to apply these concepts can help employers understand your level of expertise in software engineering and architecture. Use examples of past projects that incorporated the principles of the SOLID acronym.
Example: "When implementing design structures that require dependency injection, such as high-level application modules, I focus on each aspect of these principles regarding client needs, functionality, independence and dependence of program specifications. Using the interface segregation principle for all projects requires collaboration with the client to understand which programs and methods they use primarily.
I then incorporate the single-responsibility principle to ensure each class I design within the application follows only one function to better support usability. High-level modules within several applications I completed also required the dependency inversion principle, allowing me to create system parameters dependent on abstractions. These approaches to following the SOLID principles have helped me complete many long-term development projects within strict timelines and with reductions to project budgets."
In which scenarios would you or have you used dependency injection?
The interviewer may ask this question to assess your understanding and application of the SOLID principles of software architecture. Use your answer to highlight additional instances when you relied on your knowledge of real-world applications of the SOLID principles to incorporate this method of coding to reduce continuous updates.
Example: "Dependency injection allows me to implement the SOLID principles much more effectively by decoupling object usage and creation from each other. This action allows me to reduce the frequency at which I update program classes when dependencies change, giving me better control over the coding in programs I did not develop. Additionally, I've completed several projects recently that required dependency injection as an approach for resolving high-frequency updates that caused system lag. By adhering to the dependency inversion principle, dependency injection allowed me to reprogram system classes to update manually."
When would you use a component-based design?
This question tests your ability to discern when to use certain approaches for designing software architecture. Give examples of development projects you've worked on that required component-based architecture for increasing the reusability of various features and application properties to better support successful outcomes.
Example: "In my last role, I implemented a component-based architecture to achieve a reusable application for a large client contract. By breaking down the entire program design into both logical and functional components, I was able to define communication interfaces for improved usability by decomposing components by property, event and method of class. These approaches to component architecture helped me reduce the total cost to the client for the software product and allowed me to reduce the costs of routine maintenance my teams performed to keep the client's program operational."
What are some benefits you have gained from integrating SN architecture?
Employers may want to know the accomplishments you've made using various software development structures. Showcase your problem-solving skills and attention to detail in your answer by explaining why you implemented a shared nothing architecture and the success you achieved.
Example: "The shared-nothing architecture is beneficial for distributing a computational approach, where I can establish independent nodes that are self-sufficient and require no single points of contention within the system. SN is highly scalable, which has allowed me to achieve multiple results for past organizations.
One client I worked with required a large-scale e-commerce website where I used SN architecture to prevent single bottlenecking between sales pages and funnels, increase linear scalability and establish independent memory and file storage. On the client's e-commerce website, the independent nodes meant that failure within one node, such as a product page load, didn't affect any other nodes, resulting in continuous functionality**."
How would you group large development teams and allocate tasks for long-term or continuous software builds?
The interviewer may ask a question like this to evaluate your leadership capabilities, your delegation skills and your ability to motivate and influence development teams. Describe any methods you use for initiating long-term projects and how you approach making decisions about team roles and responsibilities.
Example: "The most successful methodology and framework I have applied in directing development teams are the Agile frameworks with Scrum implementations. Following the methodology of Scrum and executing continuous sprints has helped my teams and I achieve greater success, both in product deliverables and in the efficiency with which teams complete projects.
Using the Scrum method for larger teams, I can create groups of three to five individuals to form cohorts. Each cohort is then responsible for completing specific tasks within a development project, and I use Scrum meetings to ensure all teams are completing their objectives on time. I also favor this approach because it allows me to evaluate both team and individual performance and review the strengths of our strategies and execution of client projects."
If our company wanted to build an online catalog, what steps would you take to design it?
Interviewers also want to know that you can identify their organizations' specific needs and plan strategies to boost successful outcomes. Use your answer to showcase what you already know about the company you applied to and how this information can help you determine the best implementations for creating the organization's online catalog.
Example: "From my understanding of the organization, the online catalog would require a single master list of departments to provide product listings for each category. For instance, for the "engine parts and components" department, I would create a sub-catalog with product pages for each item in the related inventory. Within each product page, I would then create sub-units, depending on the specifications of each item, like colors and sizes. Depending on the pricing structure and lead-in for online payment processing, I would then implement standard encryption code to establish secure payment architecture within the catalog payment portal."
