As for interviewing, beyond the basics of showing that you have some relevant skill/experience, there are two key things to convey:
1. Your enthusiasm for the company itself (its product/service/industry, etc).
2. Your enthusiasm for the role itself (specific application/service/technologies, teammates, etc).
You want to convey that you are excited, motivated, and "coachable" in areas where you're lacking. The best "hack" here is to look for companies and roles that you are genuinely excited about.
Be as blunt as you have to in conveying these points. Don't expect interviewers to be good at reading your signals. If you have to, just flatly state that you are excited, motivated, eager to learn, etc. to every person you talk to.
Don't overdo it but make sure this is successfully conveyed.
People are much more likely to hire someone if they seem like they'll add energy to the team. Even in cases where their skills/experience alone don't necessarily justify the hire.
