Common Embedded Developer Interview Questions

What are your experience with embedded systems?

There are a few reasons why an interviewer might ask about an embedded developer's experience with embedded systems. One reason is to gauge the level of experience and expertise the developer has with this type of work. It's important to know whether the developer has extensive experience working with embedded systems, or if they are just starting out. Another reason might be to see if the developer is familiar with a particular type of embedded system that the company uses. This could be important if the company is looking for someone who can hit the ground running and doesn't need to be trained on the specific system.

Example: “I have experience working with embedded systems in a variety of contexts. I have experience with both low-level programming (e.g., writing drivers or firmware) and high-level applications development. I am also familiar with a variety of hardware platforms, including microcontrollers, DSPs, and FPGAs. In addition, I have experience with a number of different development tools and methodologies, including RTOSes, cross-compilers, and debugging techniques.”

What are your experience with programming languages?

An interviewer would ask "What are your experience with programming languages?" to an Embedded Developer because programming languages are important for developing software for embedded systems. Embedded systems are often designed to perform specific tasks, and programming languages are used to create the software that tells the system what to do. Different programming languages have different features that can be useful for different tasks, so it is important for Embedded Developers to have experience with a variety of programming languages.

Example: “I have experience with a variety of programming languages, including C, C++, Java, and Python. I am also familiar with assembly language and have used it to develop embedded systems.”

What are your experience with debugging tools?

The interviewer is trying to gauge the candidate's experience with debugging tools and their ability to use them to solve problems. This is important because debugging tools are vital to the development process and can help identify and fix errors in code.

Example: “I have experience with a variety of debugging tools, including gdb, valgrind, and strace. I am familiar with using these tools to debug both programs and systems. I am also familiar with using system-level tools such as lsof and netstat to troubleshoot network issues.”

What are your experience with hardware platforms?

The interviewer is asking about the Embedded Developer's experience with different types of hardware platforms to gauge their level of expertise. This is important because it allows the interviewer to understand the Embedded Developer's ability to work with different types of hardware and troubleshoot any issues that may arise.

Example: “I have experience with a variety of hardware platforms, including 8-bit microcontrollers, 16-bit microcontrollers, and 32-bit microcontrollers. I am familiar with the capabilities and limitations of each type of platform, and I have experience programming on all three types of platforms. In addition, I have experience working with a variety of other hardware, such as sensors, actuators, and communication devices.”

What are your experience with software development methodologies?

There are many different software development methodologies, and each has its own strengths and weaknesses. By asking this question, the interviewer is trying to get a sense of the applicant's experience and comfort level with different approaches to software development. This is important because the methodology used can have a significant impact on the success or failure of a software project.

Example: “I have experience with a variety of software development methodologies, including waterfall, agile, and lean. I am familiar with the benefits and drawbacks of each approach, and I am able to adapt my work style to fit the needs of any project. I have found that agile methodology is particularly well-suited to embedded development, as it allows for rapid iteration and constant feedback from stakeholders.”

What are your experience with software development tools?

There are many reasons why an interviewer would ask this question to an embedded developer. It could be to gauge the developers' experience with different tools, to see if they are familiar with a specific tool that the company uses, or to assess their ability to learn new tools.

Embedded developers often need to use a variety of software development tools, depending on the project they are working on. For example, they might use a compiler to translate their code into machine code, an assembler to create and manipulate object code, and a debugger to find and fix errors in their code.

The ability to use different software development tools is important for embedded developers because it allows them to work on a wide range of projects. It also makes them more adaptable and able to learn new tools quickly, which is a valuable skill in the ever-changing world of technology.

Example: “I have experience with a variety of software development tools, including IDEs, compilers, linkers, and debuggers. I am familiar with both open source and commercial tools. I have used Eclipse, GCC, GDB, and Makefiles for development on Linux platforms. I have also used Visual Studio and Windows Driver Kit (WDK) for development on Windows platforms.”

What are your experience with project management tools?

An interviewer would ask this question to an embedded developer to gauge their experience with project management tools because it is important for the role of an embedded developer to be able to manage projects efficiently. Project management tools can help developers track deadlines, progress, and dependencies, which is essential for keeping projects on schedule. Furthermore, many embedded development projects require coordination with other teams, so being able to use project management tools to facilitate communication and collaboration is also key.

Example: “I have experience with a variety of project management tools, including Jira, Asana, and Trello. I am familiar with the features and capabilities of each tool, and I am able to use them to effectively manage projects. I have also used other tools, such as Basecamp and Redmine, but I am most comfortable with the three mentioned above.”

What are your experience with quality assurance tools?

The interviewer is trying to gauge the applicant's experience with quality assurance tools and how comfortable they are using them. This is important because the embedded developer will need to use these tools to ensure that the software they are developing meets quality standards.

Example: “I have experience with a variety of quality assurance tools, including static analysis tools (such as Coverity and Klocwork), dynamic analysis tools (such as Valgrind), and test coverage tools (such as gcov). I have also used a variety of code review tools (such as Gerrit and Phabricator) to perform code reviews.”

What are your experience with configuration management tools?

The interviewer is asking about the Embedded Developer's experience with configuration management tools because it is important to know how the developer will manage changes to the software they are developing. Configuration management tools help developers keep track of changes to the code and ensure that the code remains consistent across different versions.

Example: “I have experience with a variety of configuration management tools, including Puppet, Chef, Ansible, and SaltStack. I am familiar with the basics of each tool, and have used them to manage both small and large deployments. I am also familiar with advanced features such as hiera data and templating.”

What are your experience with build tools?

There are many different build tools available for embedded development, and each has its own strengths and weaknesses. By asking this question, the interviewer is trying to gauge the candidate's familiarity with the various build tools and their ability to select the appropriate tool for the task at hand. This question is especially important for embedded developers because the build process can be critical to the success of the final product.

Example: “I have experience with a variety of build tools, including Make, CMake, and Ant. I am familiar with both traditional and cross-compilation toolchains. I have also used a number of scripting languages to automate build processes, such as Bash, Python, and Perl.”
