After seven 45-min interviews plus an initial long conversation with a recruiter, and after getting positive feedback after each round, I was told that after reevaluating their team's technical needs, they would not be moving forward at that time. So what had been an enjoyable process for the most part turned out to be an enormous waste of time and effort (and their own interviewers' as well!). No idea if they understand that --or care; obviously I would have appreciated if they had stopped the process much earlier.

HR takes a a 25 question technical interview (yes thats right , HR). Then there is another phony interview with engineer who will ask questions about functional programming. Ask same questions similar to what others have reported. Then they will send a rejection email. Just avoid it looks more of a scam to hire ppl on H1b. They are conducting interviews just to follow process and show that ppl were not available for jobs. Take a good look at their h1b salary , they are all in & around 120k which is a poor salary for SFO region. Their sole aim seems to hire H1b to keep cost low.
