A) Likely burn out

B) Have been wanting to try something out on my own as well

This was the first time for me in a FAANG and noticed one new joiner young colleague had this personality trait of being overtly overly positive about everything they were involved in and they did and making it a point of making it known to all of the universe. Not saying they didn't deliver or were not smart, instead quite the opposite. But goes without saying, all the positivity being projected, personally for me was a bit tiresome.

In the manager's mind I think this created an expectation for similar behaviour from the not-so-young members in the team (a.k.a me) I suspect another team member switched team immediately due to this.

In mid-40s I have little hope that I will find another job (can still grind leetcode but...) and have been thinking about getting into another line of work altogether.

But coming back to the main topic. What do rest of the people around here think about this...

1) Has "The Brag" become a requirement in tech world these days? I wasn't expecting this in a FAANG and didn't experience it until the above described events but then that did definitely change things around for me and I guess for others too.

2) If it is a requirement then what strategy/tactic works best ? Being an introvert, how do I adapt.

(I will be speaking to a therapist as soon as I get employed again but since I am living off savings currently I am resorting to "free" sources of advise)
