First round basic unity and oops, c# programming theoretical questions Second round - coding round with a lengthy program with some theoretical questions - interviewer didn’t know the logic himself so he expected me to complete the program and get it to executable state. He then tested if the logic is fine by passing inputs and executing program, by then it was more than 1.30hrs which had already made me bored of the interview. I believe interviewer should know the logic and only then he can analyze the skill of a developer with hints. Overall not a write way to take coding interview and interviewer himself isn’t skilled enough to judge anyone else.
