Our candidates report that Arm is less interested in flashy algorithms than in whether you truly understand the systems underneath them. Across experiences, the same pattern shows up: OS and computer architecture fundamentals come up repeatedly, with direct probing on pipelining, cache, paging, and memory hierarchy. That fits the company’s hardware-adjacent DNA, and it means surface-level definitions usually aren’t enough — interviewers seem to push until they hear how the pieces actually behave in a real machine.
We’ve also seen that the coding bar is practical rather than exotic. The problems tend to sit in familiar territory — linked lists, matrices, strings, trees, graphs — but candidates note that the real test is whether the solution is clean and stable under pressure. One candidate specifically called out that the interviewers cared about the fundamentals behind the code, not just the final answer. That same theme appears in the resume discussion too: they want you to explain past work clearly and connect it back to technical choices, especially when the conversation shifts into architecture-related follow-ups. In other words, Arm seems to reward candidates who can move comfortably between code, systems, and the reasoning that ties them together.

Real interview reports from people who went through the Arm process.
I went through a pretty straightforward process that started with an online test and ended with two interview rounds on the same day. The test had 30 multiple-choice questions plus 2 coding problems, and the coding part leaned on strings, graphs, and trees. After that, I had two offline interviews back to back, both focused on OS concepts and DSA. The OS questions were very much the kind you’d expect from a computer architecture-heavy company: pipelining, cache, paging, and memory came up directly, so it wasn’t enough to just know definitions at a surface level.
The coding questions in the interviews were not especially exotic, but they did check whether I could write clean solutions under pressure. I was asked things like spiral matrix and reverse a linked list, so I’d recommend being comfortable with common interview patterns rather than trying to memorize tricks. In the final stage, there were also more resume-based questions and a few technical follow-ups tied to computer architecture. One thing that stood out was that the interviewers seemed to care a lot about how well you understood the fundamentals behind the code, not just whether you could get the right answer quickly. Overall the process felt fair and pretty aligned with the role, and I got the offer after the full loop. If I were preparing again, I’d spend extra time on OS basics, especially memory hierarchy and paging, and make sure I can solve standard linked list and matrix problems without hesitation.
Prep tip from this candidate
Focus on OS fundamentals like pipelining, cache, paging, and memory hierarchy, since those came up directly in the interviews. Also practice standard DSA problems such as spiral matrix and reverse linked list, and be ready to explain your projects clearly in the final round.

Synthesized from candidate reports. Individual experiences may vary.
The process starts with an online assessment delivered through a link, often in a recorded HireVue-style format. Candidates typically answer around 30 multiple-choice questions and 2 coding problems, with the coding focused on common DSA topics like strings, graphs, trees, and basic LeetCode-style patterns. Some versions also include aptitude-style prompts, basic electrical questions, and a selection-style question.
Candidates who pass the screen move to two back-to-back technical interviews, often held on the same day. These rounds focus heavily on data structures and algorithms plus operating systems fundamentals, including pipelining, cache, paging, and memory hierarchy, along with coding questions such as spiral matrix and reverse linked list.
The final stage combines technical follow-ups with behavioral and resume-based questions. Interviewers may dig into past projects and CV details, and some candidates reported switching between C++ and Python during the discussion, so being comfortable explaining your experience clearly and coding in more than one language can help.
