It was an online interview. Since I am from an Electronics background they didn't ask much only the basics of oops, and c programming were asked. They asked about my final year project and its applications.

Asked about Data structures concepts like lists, Arrays, Stac, Que, trees, graphs, hash tables, loops concepts like if, if else, else if ladder, switch, while, function, recursion and asked me to write the code to find the sum of the digits of an array.
