"The more time I spend on the discussion the better starting point for negotiation I have." Ding ding ding ding! You discovered the same thing I have. Put me though six rounds of interviews. I have plenty of time. If I didn't think the job was a good opportunity I wouldn't have applied in the first place. But I know after the sixth round if you still like me, there's a close to 0% chance you have any other candidates waiting around. You have a lot of leverage as a candidate if you go through a long interview process. It also buys you time to interview at multiple other places in parallel.
