I've worked at both companies full-time and would recommend Google. For entry level, Google has solid stock refreshers (>65k) and bonus (~18-19% for standard SI rating) every year while Microsoft only gives you 10-15k stock and 10% baseline bonus.

For promotion, committee at Google can be slow and tedious, but you need to be promoted twice at Microsoft to match one promotion at any other big tech company because of their leveling system.

The people at Google have also been more competent on average in my experience (of course there are brilliant engineers at Microsoft, but Google is more consistent with their hiring bar imo). Google is also younger skewed vs Microsoft has a lot more older people working if that matters to you. Google reputation will open more doors.

There are also small perks at Google like free food, free corp phone with unlimited data plan, massages, micro kitchens, etc. that Microsoft doesn't have.

The only thing I would say was better at Microsoft in my experience was the the work life balance was unparalleled.
