My Time at Snap
We have all worked for a "John" in the industry. The big systematic problem is that after being fired from Snap (probably after already collecting massive paychecks and a hefty chunk of equity), he will go to another big tech company and impress them with his resume and bullshitting skills. They will hire him and deal with his antics for a few years, while he ruins more people's careers, then he will move on. Rinse and repeat.Also a 10/20/30/40 vesting schedule immediately stands out as a red flag for me. 25%/year vested quarterly (with a 1 year cliff) has been standard in the industry for a very long time. I would't trust a company to have my best interests at heart when it is massively beneficial for them if employees quit after 1-2 years (which is already about the average tenure at most companies of that size).
