What is Google Foobar?
Here are my solutions to the nine challenges that I got on Google Foobar. Some of the questions look scary on the first viewing but they are doable if you have some time to reflect on them. Some questions are also a bit math heavy and I didn't know the exact solutions to them. But if you can frame the problems correctly, you can easily find some literature on them.
Here are the problems that I got at each stage:
Level 1 - The Cake is not a Lie
Level 2 - Ion Flux Relabelling
Level 2 - Bunny Prisoner Locating
Level 3 - Queue to Do
Level 3 - Doomsday Fuel
Level 3 - Find the Access Codes
Level 4 - Distract the Guards
Level 4 - Running with Bunnies
Level 5 - Expanding Nebula
