How does Apple evaluates ICs? (Contrast w/ Facebook)

- Facebook has 6 month PSC cycles. - For a large part - it is metric driven. How much metric did you move? It’s less about better engineering or long term projects or project completion in general. That’s not to say for every calibration but generally that is true. I wonder: - How do ICs get evaluated at Apple? - What does the PSC cycle look like at Apple? - What does Apple care about in terms of employee expectations?
