If I could add my 2 cents, I also studied on design lab then took up a role as junior UX designer.
You won’t notice that you’re using all your theory and knowledge, like most things we studied, it becomes a foundation block, almost like a sub conscious, so you won’t be pushing theory too hard, adapting to real life tasks is actually quite an easy experience and personally for me far more satisfying. As others have mentioned, good relationships are key, but personally I found creating my own brand was my greatest strength. I was fortunate enough to work with very experienced UX people and they told me to define my character.
Will you be creative or methodical?
Do you base off data or customer feedback?
What thought processes do you fall back on for common UX tasks and why?
Defining myself this way made myself unique to my team, and of course never stop learning!
