Preparation should focus on demonstrating both your technical depth and your ability to work within a highly specialized, multidisciplinary team. Success at Aeva often depends on your ability to connect your theoretical knowledge to the specific constraints of the hardware you are supporting.

Role-related Knowledge – You must be prepared to go deep into your area of expertise. Interviewers will often ask you to discuss past projects in detail, evaluating your understanding of the underlying mathematics and trade-offs.

Technical Communication – The ability to articulate your thought process is as important as the code or design you produce. Practice explaining how you arrived at a solution, including why you rejected certain alternatives.

Systems Thinking – Aeva’s work is highly integrated; you must show an appreciation for how your software interacts with the broader system. Demonstrate that you consider edge cases, hardware limitations, and scalability in your designs.

The interview process at Aeva is typically rigorous and multi-staged, designed to assess both your technical proficiency and your fit for a fast-paced, innovative environment. You will likely start with a recruiter screen, followed by a conversation with a hiring manager or director to discuss your background and interest in the company. The technical assessment phase often involves one-on-one sessions with team members, focusing on your specific domain expertise and general problem-solving skills.

This timeline outlines the standard progression from initial contact to final technical rounds. Use this structure to pace your preparation, ensuring you have enough time to brush up on both core CS fundamentals and your specific technical niche. Remember that different teams may adjust the number of rounds, so clarify the expected process with your recruiter early on.

Technical Depth and Expertise

Technical interviews at Aeva are rarely purely theoretical; they are grounded in your actual work history. Expect to be challenged on the details of your projects, particularly regarding C++, DSP, or System Design.

Be ready to go over:

• Project Deep Dives – Be prepared to defend your design choices and explain the constraints you faced.
• Resource Management – How you handle memory, latency, and throughput in high-performance applications.
• Testing & Validation – Your methodology for ensuring code reliability in mission-critical systems.

Example scenarios:

• "Explain the trade-offs you made in your last major project regarding latency versus accuracy."
• "How do you handle memory leaks or performance bottlenecks in a multi-threaded environment?"

As a Software Engineer at Aeva, you will be responsible for the full software development lifecycle of components that enable 4D LiDAR perception. This includes designing, implementing, and optimizing algorithms that transform raw optical signals into precise point clouds and object detections. You will work closely with hardware engineers to ensure that the software stack is perfectly tuned to the underlying silicon.

You will also be expected to drive internal technical initiatives, such as improving CI/CD pipelines, enhancing simulation environments, or developing internal tools for data analysis and visualization. Communication is key; you will regularly present technical findings to cross-functional stakeholders, requiring you to translate complex data into clear, actionable insights for the business.

A strong candidate for a Software Engineer role at Aeva generally possesses a solid foundation in computer science or a related engineering field, combined with specialized experience in one of the company's core technology areas.

• Must-have skills: Proficient in C++, strong understanding of data structures and algorithms, and experience with real-time systems or high-performance computing.
• Nice-to-have skills: Familiarity with Python for scripting/prototyping, experience with FPGA/ASIC development, or background in Computer Vision or State Estimation.
• Experience level: Most roles require a proven track record of shipping production-grade software, often looking for candidates who have worked on hardware-software integration.

Q: How long does the interview process typically take? The process varies depending on the role and team, but generally, it spans from a few weeks to a couple of months from the initial recruiter call to a final decision.

Q: Are there brain-teaser questions? Generally, no. Aeva prefers to focus on your daily work, technical experience, and problem-solving abilities relevant to the job.

Q: How much should I focus on LeetCode-style questions? While you should be comfortable with basic data structures and algorithms, the focus is more on applying these to real-world engineering problems rather than solving abstract puzzles.

Q: What is the company culture like? Aeva is a fast-paced environment focused on innovation. You will be expected to be proactive, collaborative, and capable of working with high autonomy.

• Own your expertise: If you list a skill on your resume, be ready to go deep. Interviewers will often probe the limits of your knowledge on your own projects.
• Communicate your thought process: Never jump straight into writing code or sketching a design. Explain your assumptions and your approach first.
• Prepare your own questions: Use the time at the end of the interview to ask about the team's current challenges or the company's technical roadmap. It shows genuine interest.
• Research the technology: Understand what makes Aeva’s 4D LiDAR unique compared to traditional systems. Having this context will help you frame your technical answers more effectively.

Preparing for a Software Engineer role at Aeva requires a balance of technical rigor and clear, structured communication. Focus your energy on mastering the fundamentals of your specific domain while ensuring you can clearly articulate the "why" behind your past technical decisions.

You are entering a field that is pushing the boundaries of perception technology. By preparing to discuss your work in depth and demonstrating a collaborative mindset, you will position yourself as a strong candidate. We encourage you to continue exploring additional insights to refine your preparation. You have the skills to succeed—stay focused, stay curious, and good luck with your interviews.
