ARM Processors are used in a wide range of devices, from phones to tablets to wearables. They are known for their low power consumption and high performance. If you are interviewing for a position that uses ARM Processors, it is important to be prepared to answer questions about them. In this article, we will review some of the most common ARM Processor interview questions and how you should answer them.

Interviews for Top Jobs at Arm
Staff Engineer Interview
I applied online. The process took 2 months. I interviewed at Arm (Cambridge, England) in Jun 2022
Interview
Never talked to the same person, always over the phone, no news 6 weeks after a first interview, then a continuation for a different position without a word about the change.The process makes you feel like a commodity rather than an individual and makes you ponder if this is the kind of company you want to work for.

Design Verification Engineer Interview
I interviewed at Arm (Cambridge, England)
Interview
miscommunication on availability and no follow-ups. I am not satisfied with the whole interview process. More like Q/A than an interactive/discussion session. Initial phone screen was ok, but onsite has its downside.

Digital interviews After you’ve applied for an Early Careers role at Arm, our hiring team will review your application and invite you for an initial digital interview. The purpose of this interview is to learn more about your motivations and passions so we can start to get to know you better. During the digital interview you’ll be asked questions about the role you applied for in a similar way to a face-to-face interview but, rather than setting a specific time, you’ll have seven days to complete it at a time that suits you.
How it works We’ll send you a link to the HireVue digital interview platform in an email. Once you begin the interview, you’ll be asked some questions by our hiring team and either record a response using your webcam or type an answer. Depending on the role you apply for, we may also ask you to complete a short technical assessment.
Mode switching is used to change the state of the processor in order to run different types of code. For example, you might have a processor that is in user mode most of the time, but when it needs to run a privileged instruction, it will switch to supervisor mode. This allows the processor to maintain security by only allowing certain types of code to run in privileged mode.
The instruction set architecture used by ARM processors is a RISC (Reduced Instruction Set Computer) architecture. This means that the instruction set is designed to be simple, and that the processor can execute instructions quickly. The trade-off is that RISC architectures generally have fewer features than CISC (Complex Instruction Set Computer) architectures.
The bit size of an ARM processor refers to the width of the data bus. A 32-bit data bus can transfer 4 bytes of data at a time, while a 64-bit data bus can transfer 8 bytes of data. The bit size also determines the maximum addressable memory, so a 32-bit processor can address 4 GB of memory, while a 64-bit processor can address 16 GB of memory.
The Memory Management Unit is a hardware component present in ARM processors that is responsible for managing memory and providing memory protection. The MMU allows the processor to map virtual memory addresses to physical memory addresses, and it also enforces memory protection by preventing access to memory that is not supposed to be accessible.
The main difference between TMS320C55x DSPs and ARM processors is that the former are designed specifically for digital signal processing applications while the latter are more general purpose microprocessors. This means that TMS320C55x DSPs have features that are optimized for DSP applications such as a single-cycle MAC unit for fast multiply-accumulate operations. ARM processors, on the other hand, have a more traditional architecture and thus are more suited for general purpose applications.
