in-tech Software Engineer interview questions & guide 2026

Our interview process is designed to evaluate both your technical proficiency and your alignment with the in-tech culture. While every interview is unique, we look for consistent patterns in how you approach challenges.

Technical Fundamentals and Coding

These questions assess your core programming knowledge, your ability to write efficient code, and your understanding of data structures and databases.

• How do you approach designing and implementing an API?
• Can you explain the core principles of OOP (Object-Oriented Programming)?

Preparation at in-tech requires a balance of technical readiness and self-reflection. You should be prepared to articulate not just what you have done, but why you made those specific technical choices.

Technical Competency – We evaluate your mastery of your current stack and your ability to explain fundamental concepts clearly. You should be ready to discuss your past projects in detail, focusing on the specific technologies used and the challenges you overcame.

Problem-Solving Ability – We look for engineers who can break down large, ambiguous problems into smaller, manageable tasks. Show your process by talking through your logic out loud during technical and case-study sessions.

Cultural Alignment – in-tech values collaboration, professional curiosity, and transparency. Demonstrate your ability to work within a team by discussing how you have handled feedback, mentored peers, or contributed to team goals in previous roles.

The recruitment process at in-tech is designed to be transparent and professional. Generally, you can expect a streamlined journey that begins with a recruiter screen to establish your background and interest, followed by technical and behavioral assessments with team leads or hiring managers. The pace is typically efficient, often concluding within a month.

Our philosophy is to maintain a respectful and pleasant environment throughout the process. We value direct communication and aim to ensure that you have enough information about our projects to determine if we are the right fit for your career goals. We avoid "trick" questions; instead, we focus on your actual experience and your potential to grow with us.

This timeline provides a high-level view of our typical progression. Candidates should use this as a framework to manage their preparation energy, ensuring they are ready for the shift from high-level behavioral discussions in early rounds to deeper technical validation in later stages. Note that specific steps may vary slightly based on the seniority of the role or the specific team you are interviewing with.

Technical Stack and Fundamentals

This area confirms that you possess the foundational skills required to contribute immediately to our projects.

Be ready to go over:

• OOP Principles – Deep understanding of encapsulation, inheritance, and polymorphism.
• SQL and Databases – Proficiency in writing efficient queries and understanding database design.

As a Software Engineer at in-tech, you will be responsible for the full software development lifecycle. This includes gathering requirements, designing system architectures, writing clean and maintainable code, and performing rigorous testing. You will frequently collaborate with cross-functional teams, including product managers and Functional Safety experts, to ensure our solutions meet the highest industry standards.

• You will drive the development of new features while ensuring the stability of existing systems.
• You will engage in code reviews and technical discussions to maintain high quality across the team.
• You will translate complex technical requirements into actionable development tasks.
• You will participate in continuous integration and deployment workflows to ensure rapid and reliable software delivery.

We look for candidates who combine strong technical skills with a proactive, solution-oriented mindset.

• Must-have skills – Strong proficiency in at least one major programming language (e.g., C++, Java, or Python), solid understanding of database management, and experience with software design patterns.
• Nice-to-have skills – Prior experience in the automotive or safety-critical software domain, familiarity with CI/CD pipelines, and experience with version control systems like Git.
• Experience – We value both junior and senior talent, provided you can demonstrate a strong grasp of engineering fundamentals and a clear passion for technical growth.

Q: How difficult are the technical interviews? A: The difficulty is moderate and focuses on your practical application of knowledge rather than theoretical trivia. If you are comfortable with your daily stack and standard engineering practices, you will be well-prepared.

Q: What is the best way to stand out? A: Be honest about your experience and focus on the "why" behind your technical decisions. Candidates who can explain their thought process during technical challenges are consistently rated higher.

Q: Is there a specific focus on safety in the interviews? A: Depending on the team, yes. If you are interviewing for a role involving Functional Safety, expect questions about system reliability, error handling, and standard compliance.

Q: How long does the hiring process take? A: We aim for an efficient process that typically concludes in about one month from the initial screening.

• Own your projects: Be prepared to talk about your code in detail. If you mention a project, be ready to defend your architectural choices.
• Think out loud: During coding or case-study rounds, narrating your thought process is more important than arriving at the "perfect" answer instantly.
• Ask questions: At the end of your interviews, ask insightful questions about the team's current challenges or the company's long-term technology roadmap.
• Be ready for behavioral questions: Don't treat these as secondary; they are a critical part of our assessment of how you fit into our team culture.

A career as a Software Engineer at in-tech offers the opportunity to work on high-impact projects that define the future of automotive technology. By focusing on your technical fundamentals, being able to articulate your past design decisions, and demonstrating your collaborative spirit, you will be well-positioned to succeed in our interview process.
