Interview process must have been super easy. I was able to pass for a Mid-High level engineer despite having the skills "of and intern" (not my words)
Process was simple, the started with a behavioral interview and if you pass that, they schedule you to run a tech interview with a panel of possible interviewers (there were 20+ people on the invite, but only 2 showed up for me). Unfortunately I don't remember the exact question they asked, but they set you up with a scenario that you are not expected to finish before the time is up.
If you pass, this is the hiring step, which they include additional possible interviews with potential engineering managers. You get to choose from a handful of teams that are hiring, so they let you have a meeting with the managers of those teams, allowing you to ask questions about the team and try to find the best fit for you.
