The interviewers were very respectful, friendly and helpful. The difficulty level of the technical interview was between Medium to High. Overall a positive and fulfilling experience. The behavioral questions were tricky at times. My interview also included lunch. It is a good way to observe a person's manners and behavior over the meal. Be generous on Thank you's and say sorry quickly if it is your fault. Do not cut them off at any point as it is a disrespectful thing to do.
