I applied for a senior prplos developer role. I went through 2 rounds of interviews. The first round was an L1 interview where they asked about prplos and C. I passed and got selected for the L2 interview, which mainly focused on prplos, C (pointers, function pointers, and strings), Linux (even and odd number printing with Mutex usage), and WiFi (wireless client communication).

VVDN technologies is a core embedded company. There are four rounds in total. The rounds include a written test, a technical HR interview, another technical HR interview, and finally an HR interview. The first round is a written test consisting of 15 logical questions, 30 circuit questions, and 20 C language questions. For the circuit questions, a strong understanding of basic electronics concepts is essential for easy success, and notably, these are not multiple-choice questions. The C language questions are straightforward output-based questions. Additionally, a basic understanding of 16-bit, 32-bit, and 64-bit processors is required.
