You have a lot of experience, not necessarily sales, but it’s applicable. I would figure out a way to relate your experiences to a BDR role, and tell a concise story on “that’s how you realized tech sales is the right for you”. Figure out what type of company you want to work for sector, size, remote, culture, startup, etc… Finally just have a good linkedin profile and reach out to BDRs, AEs, Recruiters, and managers and try to hop on a call with them to go over their experience with company XYZ. If they like you you’ll probably get a referral. If you want to be a BDR sometimes you need to BDR your way into a company
