Very bad hiring process, super inefficient HR.
Resentful people in the HR and higher management. Always working against hiring managers because these people are treated poorly by their own management.
Engineer quality is very poor, you will know this during interviews and as customers.
There is only one product that sells, which is the xxxGate and if you are not in that team, your product doesn't matter.
People in the company report each other for resentful reasons, nobody cares about the bigger picture. Abusing the internal investigation process for getting rid of rivals and disagreement.
You will not have a healthy career in this company, also if you stayed too long, you end up getting affected by always fighting the crapy engineering practice and the unpleasant no-culture carelessness.
You will meet some genuinely unhappy people that can't get a job elsewhere in the bay area. This echos back the point why the engineering quality and HR efficiency is so low. You won't meet people you can learn from in this company. They were either already left or got caught in one of those resentful internal event that got them kicked out for wanting things to get better.
