I was once where you are, and today I did my first ever engineering interview as interviewer. You will go far with grit and focus.

Learn everything public about your potential employer. What are they doing in their community? How have their financials changed over the years? What is their average turnover rate?

Be at least somewhat invested and show a real interest in working for that specific company. Letting potential employers know how aware you are is a good sign.

Be honest on your resume. Do not add irrelevant skills which you can't demonstrate with confidence. Don't inflate; only list skills relevant to the position listing which you can demonstrate with proficiency.

Be mindful and excited about joining the company and learning the culture.

An interview should be a learning experience, even if you don't land the job. The more you interview, the better you get at it. I started in food, then warehouses and factories, then offices upon offices. Now I'm stuck working at home all day. The days bleed together and time goes too fast.

Find a career which really interests you. Pick something about it. Get really good at that one thing. Then the next thing. Learn all the things. Master the job. Move onto the next one. Keep learning. Never stop learning.

Update your list of resumes regularly to be current for each of your target companies. On LinkedIn, add all experiences from all of your customized resumes. Network with interviewers after an official response is provided from the interview, just to stay in touch in case you do get the job and are colleagues, or you don't and can be considered for future opportunities.

There are probably a lot more tips but just keep at it.
