For what it's worth, I recently left a position at Apple and I am the complete opposite of the "culture." Two key differences emerged in my reading of the author's process and my own, which I think boil down to differences between DevPub and where I worked, in what they call Internet Services in Cue's org. That's a pretty wide org, so there's vast gulfs even within, just based on the way the org was put together.
My culture screen was in-person, while I was being interviewed technically. Part of their process was getting to know me. I'm relaxed in interviews, joke around, and have a good time because at the end of the day, we need to like what we do. I find that this confidence has opened a lot of doors for me, but I do have to work very hard to project it given my internal strife. I often find that interviewers are more nervous than me, frankly, because as an industry we tend to toss people in a room who are themselves suffering from imposter syndrome and ask them to gauge someone they've never met with very little interview training. I was interviewing for one company on my third day.
I am the polar opposite of what I would consider to be someone who "fits Apple culture," in general, but it's worth remembering that there are vastly different cultures in different areas. I'm fat, I don't dress well, I'm largely unkempt if left to my own devices, I'm not a social butterfly -- put a soldering iron in my hand and I'll have a good time. I enjoy theoreticals about encryption and side channel attacks. I identify more with Woz than Jobs. Universally, across the board, every time I told someone I'm an engineer at Apple I got the look up and down and "you are?" in reply. I think people have an image of Apple that's formed from the typical customer and perhaps the retail folks; while that's true to an extent (what's served at Caffe Macs is an often great example, but you can find a kick-ass burger if you know which one to go to), I didn't find that Apple struck me as especially hipster or faux-cool or however you want to think of it. Again, maybe my area, but typical Web startup people generally break that way, so I would have expected Apple to reflect it, but no. That's neither here nor there and represents a very compartmentalized view. (I didn't work on Infinite Loop, and when I made journeys over there I got a different feeling, so that might be related.)
Just based on my own experience, I think team fit goes way over culture fit, and I don't think OP's experience sounds like a culture screen.
The other difference is that my process was practically a mirrored copy of Google's, with recruiter courting, technical screen by the recruiter, deeper screen by the #2 on the team, in person interviews. I interviewed for two different teams at Apple (one no-hired me, which was fun because then I was responsible for some of their stuff), and the process was nearly identical, except the no-hire team put a pair of people in the room and my accepting team put only one for each interview. At no point was FaceTime ever used. In fact, I wasn't aware that was a norm anywhere, but I admit that my purview was limited to my area.
