I was watching Day in the Life of a Facebook Software Engineer by Patrick Shyu, and could relate from the points he makes from 4.30 to 7.30 min in the video.
If you are someone who has been dreaming about working for a FANG or even a late-stage startup (1000+ employees), you should ask yourself if you are okay with some of the things which you will have to do as part of the job.
Note: I think a lot of videos Patrick makes are kinda lame and clickbaity. I disagree with most of his content on diversity. Also note that since he got fired from Facebook his videos are biased against the company. But once in a while, he throws a video like this which makes you think.
