First, I am sympathetic to your experience. It must be difficult.

    > I hear of interviews going on for 6-7 stages now, lasting almost 6-10 weeks.

From this story, it is clear that your market is clearly in favour of the employer. One year ago, it was a different story: half the time. Another thing that will hurt: If you are amazing, that 6-10 weeks will suddenly become 1-2 weeks. In my experience, nothing hurries the interview process more than telling an employer about late round interviews (or offers) at another competitor.
