Experience and background questions

Some positions require you to have a certain level of experience before applying. Experience and background questions allow employers to assess your industry knowledge and how to interpret your skills. They may also ask about previous projects and challenges to see how you function in the workplace. These questions usually produce the most variance in answers, and include:

  • What are your strengths as a solution architect?

  • What highly innovative solution have you created as a solution architect?

  • What are your weaknesses and how do they impact on your solution architect duties?

  • What is your educational background and how does it prepare you for this role?

  • Tell me about a time that a project of yours was unsuccessful and assess what went wrong.

  • What security approach do you take in your solutions?

In-depth questions

In-depth questions require you to explain or describe a certain situation in the past or theoretical future. These questions help interviewers gauge how you approach certain scenarios by encouraging you to apply industry knowledge. Some in-depth software architecture interview questions include:

  • What did you do to ensure that your new standard was active in your last role?

  • Describe a time that you diagnosed the cause of an operational malfunction and fixed it.

  • How can you improve existing software?

  • Describe a time you had to collect data to solve a problem and how you did it.

  • If a client doesn't agree with your assessment, what do you do?

  • What tools might you use to decipher code?

  • Show me a project that demonstrates your coding skills

  • Determine the output of this piece of code.

Common solution architect interview questions and answers

There are some solution architect questions that are more commonly asked than others. This is because interviewers want to know if you're aware of certain processes and whether you're proficient in software operation. Here are some common questions that interviewers may ask and how to answer them:

1. Why do you need clustering?

This question is important, as it assesses whether you're familiar with software architect processes. This question also tests your understanding of how and why they're used. Make sure that you answer this question clearly and in your own words.

Example: 'Clustering allows software architects to achieve 100% availability for server software. In the event that one hardware structure fails, it prevents the chance of services becoming completely unavailable by running a service through multiple outlets. This means that hardware failures or malfunctions are more easily targeted and the correct resources can fix the problem'.

2. What is the most innovative solution you've proposed?

Your past innovative solutions demonstrate your experience with new technologies and show interviewers how you apply them to your work. This question also allows you to showcase your creativity and the ways you respond to unusual situations. Be unique when answering this question by discussing a non-obvious solution.

Example: 'When I worked at Business Company, I had a client that was an insurance provider. The client website focused on detailing the different insurance solutions available to customers and encouraging them to select the right option for them. Since choosing insurance can be tricky, the client wanted to install a feature that allowed customers to view previous insurance plans they'd looked at. Therefore, I created a solution whereby customers could create an account and save their profile for their insurance plans. This led to an increase in customers.'

3. What does the CAP Theorem actually say?

This is another question that requires you to demonstrate your industry knowledge. Provide relevant and concise information and give your answer in the simplest terms. Also, review industry terms before your interview.

Example: 'CAP stands for availability, consistency, and partition tolerance. The theorem states that it's impossible to build a system using asynchronous networks that demonstrate these three properties. This means that the system doesn't always respond to requests and fails to achieve the same expected results every time'.

4. What is computing?

As a solution architect, it's your responsibility to keep up with next-generation technologies and incorporate them into your solutions. This question allows the interviewer to determine whether you can implement internet-based technologies. Explain your definition by outlining some benefits and distinctive features of cloud computing.

Example: 'Cloud computing allows you to access digital information and program online. As an internet-based technology, it delivers on-demand services such as applications and processing power over the Internet. It uses self-service billing, scalability, and elasticity. When implemented properly, it's highly cost effective and enhances access speed'.

5. How can you protect against an injection attack?

This question asks you to demonstrate your ability to come up with viable solutions as and when they occur. You can show your knowledge of injection attacks and provide efficient solutions against them. Keep in mind that there are multiple ways to protect against injection attacks, and you're not required to outline them all.

Example: 'You can protect against injection attacks by avoiding the use of dynamic Structured Query Languages, or SQL. I would continuously monitor SQLs that are in operation by assessing their connection to web applications'.

6. Describe your protocol for ensuring security.

Security is the utmost priority for businesses, and they usually hire solution architects to guarantee it. Therefore, cybersecurity and data protection management are key skills that software architects can demonstrate in an interview. Prepare to explain your protocols if there are additional questions about them.

Example: 'Data backup needs to take place daily to secure cloud-based technology information. I also accompany this with virus protection installations and continuous monitoring. There are several cloud edge security measures I would consider implementing too to protect online platforms where they're most vulnerable to malware'.

7. What is elasticity?

Elasticity is a feature of many internet-based solutions, including cloud computing. Understanding the characteristics of next-generation technologies ensures you can draw upon them according to their abilities and assess how different properties can help solve a problem. Make sure your answer is concise and relevant to the question.

Example: 'Elasticity means that a system automatically scales up or down to meet resource demand as they're added or removed. This means that the system is adaptable through automatic resource management, which can aid system scalability'.

8. What can a solutions architect do to support functional analysts?

Functional analysts and solution architects usually work alongside each other in business settings. You want to show the interviewer that you can successfully hone your abilities to service the needs of functional analysts, and the ways you would do this. Answering this question well can indicate to your interviewer that you have a deep understanding of your responsibilities.

Example: 'To foster good communication and collaboration between myself and functional analysts, I believe it's important to be approachable and to show enthusiasm when helping them with solutions. It's sometimes necessary to take on a leadership role to ensure your team adheres to deadlines'.
