Software engineer here to say I show up to an interview in similar attire (I ask the recruiter what the expected attire is so I may dress slightly more or less formal depending on that), but after that I’m thankful there’s no dress code because I dress in a T-shirt and gym shorts basically all day every day barring weather concerns.

I never would have thought to call his outfit sleazy or even bad.

I would even tend to call him “overdressed”.

Whenever I had in-person interviews my go to was jeans, sneakers and a presentable t-shirt (plain color, or a small logo, no metal bands or similar). Everything in good condition and clean. An unbottoned casual shirt on top, if winter.

Usually “know your shit and don’t be an embarrassment” is the bar to clear in IT.
