It'd be nice to use more inclusive gender-neutral language, or at least alternate she/he pronouns and avoid phrases like "Don’t be that Guy." Perhaps "Don't be that Candidate" or "Don't be that Person" or "Don't be that Engineer."

Really good article with solid tips. Structure, in-depth understanding of the topics and timing are really crucial for those type of interviews. I have also created System Design Template which is generic enough to be used for any interview but also FAANG companies.

This was really enlightening. Thanks for the information. I'll be sure to carry it to my next DevOps interview.
