We’re talking here about engineering role after all.
where? seemed like general advice.
Even then, thee aren’t mutually exclusive. your competence will affect how people see you on a personal level, at least at work. And your competence affects your ability to be given problems to own. You’re not gonna give the nice but still inexperienced employee to own an important problem domain. they might be able to work under the owner and gain experience, though.
Documentation and presentation are highly undervalued, and your ability to understand and spread that knowledge can overcome that lack of experience to actually handle the task yourself.
in rough order of important:
if you have no previous job, then yea. It’s rough. The first job is always rough, and even in software that’s no exception. You will want to talk about decisions and features you worked on in personal projects for that stuff. And of course, really nail down your fundamentals; they really drill you with those interview questions as a junior.
If you have a job, then talk about that. Maybe there’s some NDA, but you can talk about some problem in general terms and what you needed to do to solve it. You’re not expected to do anything crazy as a junior, so your answer relies more on you knowing how to work in a team than novel architectual decisions.
Personal example: my first job was at a small game studio and my non-BS answer would be that I simply did bug fixes for a game. Nothing fancy, probably something an intern can do.
But interview spin: doing those bug fixes
Best of luck
