The last one was 2 quick phone calls the same week. The third call was what laptop I wanted and where should the send it.
I was working in tech in the 90s and interviewing was just a chat on what I'd like to do, what they need done and if it looked like a match, let's do it. And I'll argue that jobs were more technically difficult then (assembly language, C, kernel work, attention to optimization since hardware was slow, etc) compared to the typical job these days of gluing AWS components together for yet another CRUD app functionally identical to every other.
At the end I got 5 offers to choose from out of the 8 companies I was doing interviews with, and I would've probably got all 8 offers if they didn't give a time limit to get back to them.
All of this took me about 2 hours a day of work, but I have to admit that these are all startup/medium level companies, if you're looking to get into FAANG that's another story.
Because I fucking hate the interview process. Video interview, phone screen, take home test, management interview, team interview, dozen technical interviews. It's a full-time job to look for another job. So the slightly annoying job I have is way less annoying than searching for another one.
Rant over.
