Best/Your Strategy - Slice time between side projects, new language try out projects, interview prep effort

Folks,

Would love your thoughts/ current_working_plan for how to slice time between different types of efforts as a senior software engineer (having a day job). The goal being to become a better engineer and work at a challenging (FAANG) company.

Firstly, I have sliced all efforts into three main types:

• side projects with familiar language - to ensure speed of implementation

• new language involved projects - To learn new languages

• Be interview ready - Leetcode, etc

  My questions:

• Firstly, is the above list complete?

• Secondly, Is it fair to multiplex all of the above effort types?

• If not, what do you suggest as the ideal/your_current_working_plan?

  Thanks
