I am a software engineer and I usually get this question and the end of a long interview process. After hours of tough technical sessions, by the end of the day I'm ready to go home and decompress. Yes, if I've done well on the coding tests, I usually have a manager come in and say "relax, no more coding questions, I just want to have a chat." Whereupon follows a set of open-ended questions with no right answers. The king of these is "what do you want," or "what are you looking for in your next job" type.
Are these money questions, or questions about what motivates me, or something else? How do I answer them?
