The interview consisted of a technical round where I was asked questions about digital electronics, microcontrollers, IoT architecture, communication protocols (such as UART, SPI, and I2C), and general programming concepts. The discussion also covered Python programming and commonly used libraries, along with questions based on my projects and internship work. The interview focused on both theoretical understanding and practical implementation. Overall, the process was structured and moderately challenging.

i had applied for the post of trainee engineer through my campus. There will be a test followed by 2 rounds of technical interview. Most of the questions was from the core basics.
