Manager might not be a person who you can look up to, depends on your luck, depends on the team, but slowly accountability is being brought in this aspect from the leadership by cleaning up old and inefficient leadership at least at the Sr directors and above levels
Might have to work with 2 different managers, functional manager for your day to day work and a HR manager who manages your performance at your work location, very frustrating as no one is accountable for your career in such cases and you need to be really serious about your career and performance growth and be mainly driving it
The morning and late evening meetings you might get into as there is very heavy cross firing always happening among teams sitting in India and US
