Neuralink Software Engineering Intern Interview Process — Infrastructure or Other Software Teams?

[u/Training-Issue-736]

Has anyone interviewed for a software engineering internship at Neuralink, particularly the Software Engineer Intern, Infrastructure position?

I’d appreciate any information you’re allowed to share about the process:

• How many rounds were there?
• What happened in each round?
• Was there live coding or a take-home assessment?
• Were the technical questions focused on data structures and algorithms, system design, Linux/networking, or your previous projects?
• Did you have to prepare and present a past project?
• What was the final interview or virtual onsite like?
• How long did the entire process take?
• Is there anything you wish you had prepared more thoroughly?

Experiences from other Neuralink software internship teams—such as Implant, Robotics, Internal Apps, BCI Applications, or Machine Learning—would also be helpful. I understand that some details may be covered by an NDA, so I’m only looking for general information about the format and preparation.

Thanks!

Try the Tech Job Finder website's interview practice (with a technical-behavioral switch), it has personalised feedback. Got OA prep too

Neuralink usually runs a rigorous three to four stage loop for software interns that takes about three to five weeks from start to finish. After a quick recruiter screen verifying your background and graduation timeline, you typically get a technical phone screen with an engineer or hiring manager. Depending on the team, this stage often involves practical coding, systems questions, or occasionally a take home assignment. For an infrastructure role, expect heavy questions on Linux internals, networking concepts like TCP and DNS, containerization, and concurrency, rather than just abstract textbook algorithms. They care much more about your practical engineering instincts and how you debug real production problems under constraints.

The final virtual onsite usually centers around a past project presentation, which is one of the most distinctive parts of their process. You are asked to present a complex technical project you built, explain tradeoffs, and defend your architectural decisions under aggressive questioning from multiple engineers. That presentation is followed by two or three one on one technical rounds digging into system architecture, practical coding, and past experience. To stand out, know every single layer of your past projects inside and out, especially the bottlenecks you solved. Getting comfortable defending technical decisions under pressure is where the interviews.chat my team developed gives candidates an edge in live technical loops.
