No. 1 ➞ Don’t make a generalized CV and paste it everywhere.
No. 2 ➞ Design a CV that meets job requirements, and avoid using premade templates. Hire a professional, provide your details, and get a customized CV.

No. 4 ➞ Prepare for the interview, research the industry/department you are going to work in, and their problems. Answer them in the interview with confidence.
