Hi, I am a ca to broadcom transitioned employee and let me try to answer what I can.
When do you get pay reviews/ pay rises?
In July, but be aware many got only once in last 4 years(2020-23), thanks to COVID and recession this year and massive share price growth.
When are promotions within the year?
November in General, but in case of exception, it can happen anytime through year.
When are you awarded bonuses? ( are bonuses mainly rsu’s? Or money?)
Bonus is relative to your job level and ranges from 10-30% of your package for most employees. They will be paid in December salary as you need to wait for year end numbers to determine company performance component and your division component.
RSUs are awarded in march.
How many day’s annual leave do you get?
I believe 25 days for Europe and India.10 sick days. Not sure about other geo.
What’s the grade structure?
Are you talking about the job levels? For IC, it's 8 levels.
