My job is considered both, it involves programming (mostly database stuff so far) but is considered IT because we respond to tickets from users and employees to fix issues in the existing code. Or we write new code to create reports, update the database, or something else related to the data.
I already feel like an imposter and like I shouldn’t have gotten the job, I did the same at my internship where I compare myself to all the PhDs who have been there 15 years and think I am nothing compared to them. But then I remember that at one point they were as inexperienced as me.
