The short answer
Almost nobody starts in RevOps. People arrive from sales development, marketing ops, customer success ops, finance, or a Salesforce or HubSpot admin seat, and the common thread is that they were already solving process problems where they sat. So build proof rather than applying cold: take over the reporting nobody wants in your current job, learn enough SQL and spreadsheet modelling to pull and clean your own data, and get a CRM admin certification since it is the cheapest credibility available. It also helps enormously to have carried a bag or sat next to someone who did, because RevOps is a relationship job as much as a systems job.
