I applied online. The process took 2 months. I interviewed at SandForce (Saratoga, CA) in May 2009
Interview
Phone screen by internal recruiter
Long lapse
Phone screen by hiring manager
Traditional technical interview with manager and 3-5 staff
Long lapse
Phone discussion about position with manager
Email of contract for 2 month trial as non-employee consultant at monthly rate
Last-minute difficult heavily technical interview with CTO
The staff and manager interviews were cool, but I thought the interviewers were not very well trained in the process and feedback indicated that they jumped to conclusions about ones suitabiilty for a task without inquiry into that area.
The CTO interview was late at night, the CTO was not at all friendly, obviously very impatient with having to do the interview, and expected on-the-spot answer to a difficult algorithmic problem that should take a couple days at minimum to think through.
Interview questions [2]
Question 1
10 Gbytes of 32-bit numbers on a magnetic tape, all there from 0 to 10G in random order. You have 64 32 bit words of memory available: design an algorithm to check that each number from 0 to 10G occurs once and only once on the tape, with minimum passes of the tape by a read head connected to your algorithm.
