Now they have scheduled another more technical interview with the Director of product development in the upcoming week. I am not sure what kind of questions he would ask me. I guess the questions would be related to my development process and experiences rather than actual frontend knowledge.
Can someone guide me what kind of questions should I expect and how should I prepare?
The positive thing: You seem to have done a great job in the previous two interviews, otherwise you would already be out.
So, stay relaxed and all the best! :-)
