Obviously, you still need to do interviews, but keep some perspective when deciding. Don't overweight any one thing.
Or don't even try and make X not even intersect with anything you need.
It still puzzles me how many people opt "don't even try".
A whiteboard FizzBuzz might be actually testing for memorization, deliberate interview prep, extrovert tendencies, etc. And not for any kind of actual technical skill. Failing the FizzBuzz could also just mean high social anxiety.
They're conceptually similar to software bugs - inevitable, often surprising and impossible to fix all at once.
For life, it's that you aren't your weaknesses but your strengths. Don't worry about filling the skill hole in juggling for instance, put that time into your strengths or hobbies. Be a better you, not a more complete someone else.
For hiring though, if you've assured basic competence you're now more interested in weaknesses than strengths. You don't need the world's best person in the role, you need someone who won't bring down the group - either in their incompetence, malaise, nasty behavior, or whatever.
So when being interviewing for a role don't worry about being the best, shoot for 60% and you're golden - but do your best to avoid showing even a single red flag.
