"Resume screening focused on embedded systems experience with STM32 microcontrollers, PCB design using KiCad, and FreeRTOS implementation. Technical interview included in-depth questions about PCB design principles, signal integrity considerations, RTOS task scheduling, interrupt handling, and motor control systems. Discussed specific projects involving electric vehicle ECU development, magnetic encoder interfaces (AS5600 I2C), and PWM motor control with DRV8833 drivers. Questions also covered debugging techniques using J-Link/ST-Link, communication protocols (SPI, I2C, UART), and real-time system design patterns. The interview assessed both theoretical knowledge and hands-on experience with embedded C programming, hardware-software integration, and system-level troubleshooting."
