I never saw a more dispassionate panel of interviewers. All but one interviewer seemed to be going through the motions. There was one intro call followed by five rounds of on-site interviews.

No coding or problem-solving questions were asked at any stage. Interviewers kept asking open-ended questions from their business domain and did not allow clarifying questions. They wanted me to jump straight to the very narrow solution they already had in mind, without any of the intermediate steps. The functional requirements of design problems kept changing during the course of the interview.

It also felt as if interviewers felt compelled to shoot down everything I had to say. They did not allow me to nail down the scope of the question and kept jumping from topic to topic in order to throw me off.

I didn't feel challenged, nor did I have a good impression of the caliber of their staff. The individuals seemed to want their egos stroked and didn't appear to have a data-driven approach to assessing specific areas.

The most challenging thing you worked on was the hotel booking system. (This question was asked 5 times.)
