That is undeniably true.
The difference is that in this case I will walk in knowing very well that I need to budget time/money/energy into marketing.
Was going through some YT videos from someone claiming to have spent several years in a FAANG and they also mentioned that even the job "turns out to be a marketing" effort in no small part.
I did have a mentor in the job who was encouraging me to "demo as frequently as possible" and that made sense.
What tripped (or triggered even) me was the constant "I am so good, this thing I did made me so happy and all of you must agree" behaviour by the minute... and that was somehow being encouraged. I don't get that...
