That depends on the culture of where you're applying, and maybe what team is hiring you. When I interviewed at Google after working for a small company for 13 years, it was my first "newfangled" tech interview. I didn't know anybody in the room. And it was more than a formality. I'm a fairly terrible interviewee, and although I got hired (finally, after a very long process), I was hired at least a level below where I should have been. I blame my fuzzy memories of algorithms I haven't had to implement in 20+ years. I finally got promoted to the correct level nearly 2 years later. Contrast this with Netflix, where I found the opening via my network. I knew more than half the people who interviewed me, and the interview itself felt like it was basically a formality. Days later they made an offer that I accepted.
