Coding

In the final article of our series, we address the “old world” vs. the “new world” of code optimization. In a System Architect interview, you aren’t just asked how to …

In a “Bare Metal” or System-level C++ interview, the interviewer will often test your knowledge of Resource Management. In C, you have malloc and free, which are prone to leaks …

In a standard software interview, “linking” is something the IDE does automatically. In a System Architect interview, the Linker Script (.ld) is a primary topic. It is the bridge between …

In the semiconductor industry, “The Bit” is the fundamental unit of communication. Whether you are configuring a PLL (Phase-Locked Loop), checking a FIFO status, or parsing a PCIe TLP header, …

In the semiconductor and embedded world, there is a long-standing myth that C++ is “too heavy” for bare-metal systems. As a System Architect, your job is to debunk this by …

In a standard C++ interview for a desktop role, interrupts rarely come up. In a Systems Architect interview, they are the heartbeat of the discussion. An ISR is a function …

In a C/C++ interview, the const keyword is a classic “litmus test.” A junior developer thinks const just means “I can’t change this variable.” An Architect knows that const is …

In a high-level language, a pointer is just a reference. In C and C++, a pointer is a memory address, and how you manipulate that address can either make your …

In a systems programming interview, one of the fastest ways to separate an “Application Developer” from a “Systems Architect” is to ask where a specific variable lives. In the embedded …

In a standard software interview, volatile is often described simply as “telling the compiler not to optimize a variable.” But for a System Architect or an Embedded Lead, that answer …
