It doesn't matter if one doesn't have technical skills, esp when you are from non-IT background. General questions were asked and questions from the project that you have worked on would be asked.

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.
