Not completing something simply because you dislike it is a big red flag. At work you often have to finish stuff you don’t like, you don’t want employee that will start something but rely on others to finish it.
This is generally only something a person can have certainty about in hindsight.
That seems overly simplistic.
Everyone doesn’t complete somethings because they don’t like it. Decisions and life is far more muddy and complicated than that.
But what do I know I’m a college grad who barely gets any interviews for anything.
