Same here. The bay area has now priced out professionals with families. I was looking at $40-$60k more per year for housing depending on where in the bay area I would live and I'm currently making over $120k...
I ended up not taking a job through them (I did the math and relocating to SF meant I would have a longer commute and only slightly more pay after housing my family of 6), but the process was great.
After the initial test, there is a fairly long phone/remote desktop interview that consists of:
* Writing code (on your actual machine with the tools and language of your choice!) to solve a simple problem.
* Debugging (a smallish program with 5 failed unit tests)
* General knowledge questions (databases, web (both html and http), data-structures algorithms)
The phone interview then ended with them giving you a couple of tips on answering the non-technical interview topics that a lot of engineers flub (why do you want to work here, when can you start, compensation).
The next day I got a list of over a dozen positions with the recommendation that I pick at least 5 to move on to phone screening.
The phone screenings went well (3 of them were just varients of "all the candidatese triplebyte has sent us were great, so we just want to talk about our company"). This was also my first hint that compensation would be an issue; one company was immediately ruled out because they were early stage and I can't pay a mortgage with equity.
Then triplebyte scheduled the on-sites all in the same week so that I wouldn't have to go back-and-forth to the bay area.
Ultimately Apple was the only company on my list paying enough to get me to relocate, and they passed on me.
