Hubs Software Engineer interview questions & guide 2026

Our interview process is designed to evaluate your problem-solving process and your ability to communicate technical trade-offs. The questions below are representative of the patterns you will encounter; focus on articulating your thought process rather than memorizing "correct" answers.

Technical Depth and Problem Solving

These questions assess your ability to apply fundamental computer science concepts to practical scenarios and your proficiency with the languages used at Hubs.

• What is the time complexity to find an item in a hash, a linked list, and a binary search tree?
• How would you read a huge CSV or PSV file efficiently?

Preparation at Hubs should focus on demonstrating how you apply your skills to real-world problems. We prioritize candidates who can communicate their reasoning as clearly as they can write code.

Role-Related Knowledge

• We evaluate your mastery of the tools you use daily, such as Python or modern frontend frameworks.
• Demonstrate this by explaining not just how to implement a feature, but why a specific library or pattern is the most efficient choice for the given requirements.

Problem-Solving Ability

• You will be asked to solve problems that may be ambiguous or open-ended.
• Show strength by asking clarifying questions, identifying potential edge cases, and explaining the trade-offs of your proposed solution before you start coding.

Collaboration and Communication

• Engineering at Hubs is a team sport; we value engineers who can explain complex technical concepts to non-technical stakeholders.
• During technical discussions, be open to feedback and demonstrate that you can iterate on your initial designs based on new information.

The interview process at Hubs is structured to be conversational and collaborative. We aim to understand your way of thinking and how you operate within a team. You should expect a series of stages that move from initial alignment to deep-dive technical assessments, with a consistent focus on your problem-solving style and cultural alignment.

We emphasize transparency and respect throughout the journey. While the process involves technical rigor, our interviewers strive to make the sessions feel like a professional dialogue. We look for candidates who are not only capable of writing high-quality code but who also take pride in their craft and are eager to learn from their peers.

The timeline above reflects the typical progression from screening to final offer. Use this to pace your study and ensure you are prepared for both the technical depth of the coding assessments and the collaborative nature of the design and culture interviews. Keep in mind that while the stages are standardized, the specific focus may shift slightly depending on the team you are interviewing with.

Technical Decision Making

We evaluate your ability to make pragmatic choices. A strong candidate understands that "perfect" code is less important than "fit-for-purpose" code that is maintainable and scalable.

Be ready to go over:

• Trade-offs – Why you chose one library or database over another.
• Maintainability – How you write code that others can easily read and extend.

As a Software Engineer at Hubs, your primary responsibility is to build robust, scalable software that supports our manufacturing ecosystem. You will be expected to own features from the initial design phase through to deployment and monitoring. This involves writing clean, well-tested code and participating in active code reviews to ensure the team maintains a high standard of quality.

Collaboration is essential. You will work closely with product managers to translate user needs into technical requirements and with other engineers to maintain the integrity of our platform. Typical projects include optimizing backend API performance, improving the reliability of our automated manufacturing workflows, or enhancing the user-facing interfaces that our customers interact with daily. You will be expected to stay agile, balancing immediate feature requests with the long-term goal of reducing technical debt.

A strong candidate for this position brings a solid foundation in software engineering principles and a passion for building user-centric products. We look for individuals who are comfortable with our tech stack and are eager to tackle the unique challenges of the manufacturing industry.

• Must-have skills – Strong proficiency in Python and experience with modern web frameworks; a solid understanding of database design, RESTful APIs, and version control (Git).
• Nice-to-have skills – Experience with Docker and containerization; familiarity with frontend technologies like React; prior experience in a high-growth environment or a platform-based business.
• Experience level – We value practical experience—whether through previous roles or significant personal projects—that demonstrates your ability to deliver production-ready code.

Q: How long should I spend preparing for the interview? A: Preparation time varies by individual, but most successful candidates spend a few days reviewing their own past projects and brushing up on core data structures and algorithms. The goal is to be comfortable discussing your past work in detail.

Q: What differentiates a successful candidate? A: Success often comes down to the ability to articulate the "why" behind your technical decisions. We value candidates who can explain their trade-offs and show a genuine interest in the problems we are solving at Hubs.

Q: Is the take-home assignment mandatory? A: Yes, the take-home assignment is a standard part of our technical evaluation. It is your opportunity to showcase your coding style and how you approach a problem from start to finish.

Q: What is the typical timeline from screen to offer? A: The process usually lasts between 4 to 6 weeks, depending on interview availability and team schedules. We aim to keep you updated at every stage.

• Own your past work: Be prepared to talk about every line of code in your take-home assignment. If you used a specific library or regex, know why you chose it.
• Think out loud: During technical interviews, explain your thought process. Even if you don't reach the perfect answer, we want to see how you approach the problem.
• Ask questions: Use the time at the end of your interviews to learn about our team, our OKRs, and the challenges we are currently facing.
• Be honest about your gaps: If you don't know an answer, say so, but then explain how you would go about finding the solution. We value intellectual honesty.

The Software Engineer role at Hubs is an opportunity to solve complex, real-world problems at the intersection of software and hardware. By focusing on your core technical strengths, articulating your architectural reasoning, and demonstrating your commitment to collaborative team success, you will position yourself as a strong candidate. Remember that your interviewers are looking for a colleague they can work with, not just a set of technical skills.
