Qualcomm Embedded Firmware Engineer Interview Experience

I had a comprehensive interview experience with Qualcomm consisting of four rounds: a technical round focusing on C programming and operating systems, an onsite round discussing Android-related topics, and a hiring manager round that revisited technical subjects. The overall difficulty was medium, with a good mix of theoretical and practical questions, including pointers, memory management, and Android middleware. Overall, it was an engaging process that tested both my technical knowledge and practical skills.
