This has one disadvantage: You will be working with people who don't want to work, do everything to waste your and their time and will drag you down. If you are fine with that everything is good, but if you have at least a bit of drive to achieve something great you will be very very unhappy.
If you are into those kind of generalisations you could easily argue that's not very different from working at FANG where a lot of people only care about their own career and care very little about creating good products.
