Studies show that men apply for jobs if they fulfil around 60% of the criteria on average. Women and other members of marginalized groups, on the other hand, often only apply if they meet every single criterion. So, if you think you have the potential but don’t exactly meet every point in the job description, apply anyway. Applicants of all ages are welcome.
