Pros
money, stocks, other minor benefits. Some people are nice and competent...
Cons
...other people are toxic. "Break things fast" culture, no testing culture. you need to get quickly your work in prod and if it breaks you fix it, if your manager is toxic he will blame you, if you are careful and test your stuff and he is toxic, he will push for the progress. People don't know what to do and what they are doing and why, managers don't know requirements, product managers are very few and far from engineers and nobody knows what they do. Projects start out of no idea whether they are going to be useful or not, so if you hard work on something that is most likely going to fail, your "impact" is gonna be minimal. Managers do not listen feedbacks, they shamelessly gaslight you inviting you to practice "growth mindset" while they ignore evident problems in their team/org. When Andromeda, alpha centauri and Orion align, the company hires random people with no experience at non-entry level positions. The alignment happens quite often.
