Others have already commented on this, but do you work in tech? IME getting interviewed by directors and even VPs in t-shirts is the norm. I’ve worn jeans to work my whole career. If anything, I think people in tech have a strong prejudice against people in suits (ie “obviously this person isn’t a real software engineer, they’re wearing a suit.”)
Anyway, probably not good career advice to wear a suit unless dress codes at tech companies are suddenly subject to drastic changes.
