Sales is one job that'll take just about anybody. Obviously if you want to break into tech or software sales this is not the case entirely since you need some pedigree due to competition for the roles. But even then its still possible. That aside all other sales jobs can be earned by simply applying, following up, and displaying you're competent. A big factor in sales is about handling rejection and most people don't want to sign up for that, hence the low entry barrier for sales jobs.
