I've never managed that, but everyone I know who has had some combination of the following:

- brilliant

- lucky

- juggled like 50 interview processes at once

Only one you can do anything about.

I got three FAANG offers at once 3 years ago. I stalled the first one and used it as leverage to speed up the laggards.

College recruiting can make this happen. Granted really only for new grads but it is totally normal in that setting to get multiple offers within a week or two of each other.

Feels intentional by recruiters as a part of the hiring meta-game tbh
