I applied online. I interviewed at IppoPay Technologies (Chennai) in Jul 2025
Interview
The interview process consisted of four rounds.The first round was a general written test that included questions from various domains: 5 questions from digital electronics, 5 from electrical engineering, 5 from C programming, and 5 from general aptitude. The second round was a more detailed technical written test, comprising 20 questions on C programming, 10 questions on digital electronics, and 15 questions on electrical concepts. The third round was a technical interview where I was asked in-depth questions on pointers, memory allocation using malloc and calloc, usage of typedef, and the CAN protocol. Additionally, I was tested on my understanding of data structures, specifically singly linked lists, doubly linked lists, and circular linked lists. The final round was the HR interview, where I had to explain my project in depth, including the technical implementation and objectives, along with discussing some background details related to my academic and personal profile.
Interview questions [1]
Question 1
One of the key questions they asked me during the technical round was to explain the difference between `malloc()` and `calloc()`, along with how memory is allocated and initialized in each case. They also asked me to write a small code snippet using both functions and explain how it would behave in terms of memory management and output.
Asked about buisness models and the approaches to improve buisness by providing a new idea and after which a general HR round was held to elaborate about the company, salary, work environment and the work to be done.
