Google, microsoft employees have ample free time????

It's mostly junior engineers who do this. Senior levels folks have way more responsibilities.

Lol so well said these are all entry level candidates just into Microsoft, and have started selling their courses LinkedIn being the selling platform. Good for them but this doesn't mean Microsoft has no work, sr have too much work and even manage personal time is a big challenge. If these course creators focus a little on work the workload can be reduced. Lol no offense just saying it out loud.

my employer works at microsoft at a senior level. He says he does not have much time yet he is running a business aside, goes to holidays and enjoys his life. He does not seem to have anything much to do.
