Masabi Software Engineer interview questions & guide 2026

The following questions are representative of the patterns reported by candidates. While your specific experience may vary based on the team, expect a balanced focus on your technical foundation and your ability to collaborate within a squad.

Technical & Domain Knowledge

These questions test your understanding of backend fundamentals, specifically in the context of RESTful services and transactional integrity.

• Define the differences between PUT and POST operations in a REST API.
• What are the key considerations when designing a REST API for a payment vending machine?

Preparation at Masabi should focus on demonstrating both depth of technical expertise and the maturity to work in a collaborative, cross-functional team.

Technical Competency – You must be comfortable explaining the "why" behind your code. Interviewers evaluate how you handle trade-offs and your ability to write clean, maintainable code rather than just focusing on syntax.

Problem-Solving Approach – When presented with a coding or design challenge, articulate your thought process clearly. Ask clarifying questions, discuss potential edge cases, and prioritize testing early in your solution.

Communication & Collaboration – Masabi is a team-oriented environment. Be prepared to discuss how you integrate with product managers, your approach to feedback, and your ability to explain complex technical concepts to non-technical stakeholders.

Values & Cultural Alignment – Your interviewers will look for evidence that you are a "team player." Show that you are comfortable with brainstorming, peer reviews, and the iterative nature of software development.

The interview process at Masabi is generally structured to be practical and collaborative. You should expect an initial screening call with a recruiter, followed by one or more conversations with engineering managers or technical leads to discuss your background and technical approach. The process typically culminates in a technical assessment, which often features live pair programming or a deep-dive discussion into code refactoring and system design.

The philosophy behind this process is to see how you think and work in real-time. Unlike companies that rely on high-pressure "black box" algorithm tests, Masabi prefers to see how you perform in a setting that mimics their actual day-to-day engineering environment. Expect the process to be disciplined regarding time and format, with a consistent focus on your rationale for the decisions you make.

The visual timeline above reflects the typical progression from initial screening to technical evaluation. Use this to pace your preparation; ensure you are ready to discuss your past projects in the early rounds and have your development environment and problem-solving mindset ready for the technical sessions.

API Design & System Architecture

Since Masabi operates at scale, designing robust APIs is a core expectation. You should be able to justify your design decisions regarding security, state management, and error handling.

Be ready to go over:

• RESTful principles and status codes.
• Handling concurrency in transactional systems.

As a Software Engineer, you will spend your time building and supporting the backend infrastructure that powers global transit. You will collaborate closely with product managers, QA engineers, and other developers to translate requirements into scalable, reliable code.

Expect to be involved in the full development lifecycle: from brainstorming API designs to participating in pair programming sessions and conducting code reviews. You will likely work on projects that involve integrating payment gateways, improving system performance, or refactoring legacy modules. Success in this role requires not just technical proficiency, but the ability to communicate your ideas clearly and contribute to a team-first culture.

A strong candidate for this role combines solid backend fundamentals with a pragmatic approach to software development.

• Must-have skills: Proficiency in backend languages (Java is common, though general engineering strength is prioritized), a strong grasp of REST API design, and experience with testing frameworks.
• Nice-to-have skills: Experience with high-concurrency systems, cloud platforms (like AWS), and working within an Agile/Scrum framework.
• Experience: A track record of delivering production-grade code and collaborating in a team setting is essential.

Q: How long does the interview process typically take? The process can vary, but most candidates move through the stages within a few weeks. Consistency and responsiveness on both sides are key to a smooth experience.

Q: Is the technical interview focused on algorithms? Not primarily. Expect more focus on practical tasks like refactoring, API design, and testing, rather than complex whiteboard algorithmic challenges.

Q: What is the best way to prepare for the cultural fit round? Be authentic and ready to discuss your past team experiences. Highlight instances where you were a supportive teammate, handled feedback well, or contributed to a team's success.

Q: What makes a candidate stand out? Successful candidates are those who ask insightful questions, show a clear understanding of trade-offs in their technical choices, and communicate their thought process clearly during collaborative sessions.

• Prioritize Testing: Whenever you write code during a technical session, always talk about how you would test it. It is often more important than the code itself.
• Explain Your Trade-offs: In system design, there is rarely one "perfect" answer. Explain why you chose one approach over another.
• Be Collaborative: Treat the technical interview like a real-world pair programming session. Engage with your interviewer as a partner.
• Know Your CV: Be prepared to dive deep into any project you list on your resume. Be ready to explain the technical challenges you faced and how you overcame them.

The Software Engineer role at Masabi is an excellent opportunity to work on high-impact systems that affect millions of commuters. By focusing on your core engineering fundamentals, demonstrating a collaborative mindset, and showing a clear, methodical approach to problem-solving, you will be well-positioned to succeed.
