Worldata interview questions

Applied online and a few days later contacted for a onsite interview. It was an 3:1 interview, but the overall interview was very easy, pretty much talk about your resume and personal projects. There was some technical question by one of the interviewers, his job was to stomp new candidates but he was horrible interviewer. I didn't understand the question he was asking, neither did the senior developer. I was expecting the traditional data structure, algorithm, OOP questions and some code writing but none was ask and no coding.
