The first place recruiters and employers look is your LinkedIn profile so it needs to be robust and full. I successfully took someone with little experience and an empty LinkedIn profile to attract an Amazon recruiter in 1 month and got HIRED relocation plus bonus! My career opportunities have been because of my LinkedIn profile. You marketing yourself(your brand) on LinkedIn is so crucial. Investing in your LinkedIn presence will help build your professional brand and detail the past, present, and future of your career. Your profile allows you to show your proactiveness in: your career, staying relevant and doing in-depth research on companies. Also a direct link to network with recruiters for future opportunities.
Maybe you know the industry you want to be in but not which area within the business. Get in contact with those in the profession you dream of and learn from their success. It’s not always what you know but who you know. Your network is your net worth. It is best to know someone on the inside to help you land an interview when job hunting.
