Behavioral & Project Defense

The behavioral panel is just as critical as the technical evaluation. The team wants to ensure you are a reliable, collaborative engineer who can handle the unique pressures of the defense industry.

Be ready to go over:

• The STAR Method – Structuring your answers with Situation, Task, Action, and Result.
• Conflict Resolution – Navigating disagreements with peers, managers, or external clients.
• Handling Ambiguity – Delivering results when requirements are incomplete or changing.

Example scenarios:

• "Describe a time when you were assigned to a project with technologies you had never used before. How did you get up to speed?"
• "Tell me about a time you had to make an ethical decision or adhere to a strict compliance standard in your work."

As a Software Engineer at Raytheon Technologies Corporate Headquarters, your day-to-day work will vary depending on your team, but primary responsibilities typically include:

You will design, code, test, and integrate software components for advanced aerospace and defense applications. This involves writing clean, well-documented, and highly optimized code in languages like C++, Java, or Python, often targeting embedded Linux or real-time operating systems.

You will collaborate closely with systems engineers to translate high-level system requirements into concrete software designs. You will also work alongside hardware and test engineers to debug integration issues, run hardware-in-the-loop (HIL) testing, and verify that the software meets all safety and performance standards.

You will participate actively in engineering processes, including Agile standups, sprint planning, and rigorous peer code reviews. Additionally, you will draft technical documentation, software design descriptions, and test plans to ensure compliance with Department of Defense (DoD) standards and company quality metrics.

To be competitive for this position, you must meet several strict technical and regulatory requirements.

• Must-have skills – A bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a highly related STEM field. Proficiency in at least one major programming language (C++, Java, or C#) and a solid understanding of software engineering best practices.
• Must-have regulatory requirement – US Citizenship is required for the vast majority of software roles at Raytheon Technologies, as you must be eligible to obtain and maintain a US Department of Defense security clearance.
• Nice-to-have skills – Experience with real-time embedded systems, Linux development, Matlab/Simulink, or software-defined radios. Familiarity with DoD software development standards, DevSecOps pipelines, and containerization technologies like Docker or Kubernetes.

Q: How difficult is the Software Engineer interview at Raytheon Technologies? A: Candidates generally describe the interview as average in difficulty, though it can vary by team. While you will not typically face intense, algorithmic LeetCode-style coding challenges, you will face highly detailed questions about your resume, OOP concepts, and practical system design.

Q: How long does the hiring process take? A: The interview phase itself is often very fast, sometimes concluding within a week or two. However, the period between accepting your offer and your actual start date can take anywhere from 6 to 12 months if your role requires a pre-start security clearance.

Q: Do I need prior defense industry experience to be hired? A: No. Raytheon Technologies hires many entry-level engineers and career-switchers from commercial tech. They place a high value on strong foundational engineering skills, a collaborative mindset, and your trainability on the job.

Q: What is the work culture like for software engineers? A: The culture is highly professional, structured, and focused on quality and safety. Because of the secure nature of the defense work, many software roles require working on-site in secure facilities, though some hybrid opportunities exist depending on the classification level of the project.

To maximize your chances of securing an offer, keep these highly actionable tips in mind:

• Quantify your impact: When discussing your past projects, always use the baseline-to-final metric approach. For example, "I optimized the database query structure, which reduced signal processing latency from 450ms (baseline) to 120ms (final)."
• Study the leadership: Raytheon Technologies values candidates who show genuine interest in the company's mission. Do your research, understand their main business units (e.g., Raytheon, Collins Aerospace, Pratt & Whitney), and refer to their leadership or major initiatives during your discussions.
• Be transparent about clearances: If you already hold an active secret or top-secret clearance, make sure it is prominently displayed at the top of your resume. If you do not, be ready to confidently state your eligibility and willingness to undergo the background investigation process.

• Show your thought process: If you are asked a difficult engineering or physics estimation question, do not panic. Grab a piece of paper, write down your assumptions, and talk the interviewer through your logical progression. They care far more about how you think than whether you get the exact number right.

A Software Engineer career at Raytheon Technologies Corporate Headquarters offers the rare opportunity to build software that operates at the absolute frontier of technology and national defense. The work is challenging, highly regulated, and carries immense responsibility—but it also provides unmatched stability, excellent benefits, and the chance to work on projects of global significance.

As you prepare, focus heavily on mastering your object-oriented programming fundamentals, refining your project stories using the STAR method with clear metrics, and ensuring you can discuss every detail of your resume with absolute confidence. Structured preparation is the single most effective way to calm your nerves and showcase your true engineering capabilities.
