Expect a mix of standard behavioral questions and specific inquiries about your implementation history. The following questions are representative of what candidates have encountered in recent years.

Behavioral & Experience

These questions test your past performance and your ability to integrate into the county's work culture.

• "Tell us about a time you failed on a project. What did you learn?"
• "Describe your experience working in a team environment. What role do you typically take?"
• "How do you handle a situation where you are given a task you don't fully understand?"
• "What is your preference for working inside an office versus working remotely or in the field?"
• "Walk us through a successful project you led from start to finish."

Technical & Problem Solving

These questions assess your "implementing experience" and how you approach technical challenges.

• "How do you ensure your code is secure when handling sensitive user data?"
• "Describe a complex technical problem you solved recently. What was your approach?"
• "How do you stay current with new technologies, and how do you decide when to apply them to your work?"
• "What is your process for debugging a production issue under a tight deadline?"
• "Explain the difference between a monolithic architecture and microservices in the context of a government agency."

The visual timeline above illustrates the progression from the initial application to the final selection. Candidates should notice the emphasis on both pre-recorded assessments and live panel interactions, which requires balancing independent technical performance with interpersonal engagement. Use this timeline to pace your preparation, focusing first on your "elevator pitch" for the video screen and then shifting to deep technical review for the later rounds.

Deep Dive into Evaluation Areas

Technical Implementation & Execution

This area focuses on your ability to take a requirement and turn it into a functional, scalable piece of software. The county values engineers who can navigate the entire software development life cycle (SDLC) and who prioritize reliability.

Be ready to go over:

• System Architecture – Discussing how you structure applications to be maintainable and secure.
• Database Management – Your experience with data modeling and ensuring data integrity within government systems.
• Testing and Quality Assurance – How you validate your code to prevent service interruptions for residents.

Advanced concepts (less common):

• Legacy system migration strategies
• Cloud integration in a hybrid government environment
• API security and public-facing data protocols

Example questions or scenarios:

• "Describe a time you had to implement a complex feature with limited documentation."
• "How do you approach refactoring a critical piece of legacy code?"
• "Walk us through your process for ensuring a new deployment doesn't disrupt existing services."

Behavioral & Mission Alignment

Hennepin County places significant weight on how you fit into their organizational culture. They look for candidates who are resilient, adaptable, and genuinely interested in public service.

Be ready to go over:

• Conflict Resolution – How you handle disagreements within a technical team.
• Adaptability – Your experience working with shifting priorities or regulatory changes.
• Mission Focus – Why you choose to apply your engineering skills to local government rather than a private tech firm.

Example questions or scenarios:

• "Tell us about a time you had to explain a technical problem to a non-technical stakeholder."
• "Give an example of a project where you had to balance technical perfection with a hard deadline."
• "What interests you most about serving the residents of Hennepin County?"

Key Responsibilities

As a Software Engineer at Hennepin County, your daily work will involve a mix of new development and the stewardship of existing platforms. You will spend a significant portion of your time coding and reviewing pull requests, but you will also participate in architectural discussions and sprint planning.

You will collaborate closely with Project Managers, Business Analysts, and department heads to translate policy requirements into technical specifications. For example, if the county board passes a new initiative for housing assistance, you might be tasked with updating the application portal to accommodate new data fields and workflows.

Typical projects include:

• Developing and maintaining internal applications used by county staff for case management.
• Enhancing public-facing websites to improve accessibility and user experience for residents.
• Building data pipelines that help county leadership make data-driven decisions regarding public resources.
• Ensuring all software meets strict security and compliance standards, particularly when handling sensitive resident data.

Role Requirements & Qualifications

To be competitive for a Software Engineer or Professional Engineer position at Hennepin County, candidates must demonstrate a strong foundation in engineering principles and a track record of successful project delivery.

• Technical Skills – Proficiency in languages such as C#, Java, or Python, and experience with modern web frameworks (e.g., .NET, React, or Angular). Strong SQL skills are almost always required.
• Experience Level – Most roles require a Bachelor’s degree in Computer Science or Engineering, along with several years of professional experience. For Professional Engineer titles, specific licensure or advanced specialized experience may be required.
• Soft Skills – Excellent verbal and written communication is non-negotiable, as you will be part of a large, diverse workforce.
• Must-have skills – Full-stack development experience, version control (Git), and an understanding of Agile methodologies.
• Nice-to-have skills – Experience with Azure or AWS, knowledge of accessibility standards (WCAG), and prior experience in the public sector or large-scale enterprise environments.

Frequently Asked Questions

Q: How difficult are the technical interviews at Hennepin County? A: Most candidates rate the difficulty as "easy" to "average." The focus is less on "LeetCode-style" brain teasers and more on your practical ability to build software and discuss your implementation experience.

Q: What is the culture like for engineers at the county? A: The culture is professional, stable, and collaborative. There is a strong emphasis on work-life balance and the long-term impact of your work, rather than the high-pressure "crunch" cycles often found in startups.
