Interviewing at HRL Laboratories
What the process looks like, and what HRL Laboratories is really testing for.
HRL Laboratories interviews you across both communication and deep technical work. Based on reported steps, you should expect at least one stage that includes a formal technical presentation and an extended set of technical conversations, and in some cases a full-day loop or a full-day panel interview that also includes team time and a facility tour.
The topics they emphasize are heavily technical and role-adjacent. QA Engineering Fundamentals, mechanical assembly testing and test planning are top priorities, while Research presentation and deep technical interviewing show up as the highest prominence technical areas. They also repeatedly probe test and hardware related thinking, including high voltage engineering, power electronics, test equipment familiarity, and integration testing concepts.
Across reported process steps, the interview experience is structured to validate how you learn, how you plan and design tests, and how you communicate technical work clearly. A take-home project may be used, and you are also likely to be discussed on your technical resume and your ability to go through a project deep dive and a technology discovery or learning process.
The non-obvious differentiator is that they pair deep technical subject matter, including high voltage and power electronics related areas, with a research-style presentation and strong testing mindset, such as test planning and integration testing concepts. Your communication of technical decisions matters as much as getting the technical details right.
