If I was determined to get another coding job in a large company, I realized I simply need to conform, study, and prep. It only makes logical sense for them to have this system to filter out the huge number of applicants, but for me its like a waste of my time, reviewing and memorizing the specifics of a bunch of stuff that I may continue to never use.
It's almost like my "imposter syndrome" early in my career lead me to put on a veil of self-confidence and to "try hard" to prove myself. Which actually led to positive interview outcomes (I used to ace each one I went to). Now I am confident in my skin, and don't feel the need to compensate, which, I'm realizing, actually has a negative effect on people's perception of me as an engineer.
