Google has been my dream job since I can remember, and I went to the phone interview once and failed completely. It was hard and two days later my recruiter said that was it. I was sad especially after studying for 3 months with no job after a bootcamp.

Anyways years have passed and I now have a good job as a dev, but the google dream hasn't left my mind and I plan on doing 1h a day for a year so that's around 350h total.

I'd like to ask people that preferably work at a FANG, if that time is enough? I believe those that say you need less time are either lying or have spent the other time actually learning.

How long did you spend preparing? That includes learning the ins and outs of algorithms, when to use them and being able to do them fast and efficiently...
