Don’t meet all the role requirements? Don’t worry! We value outcomes over checkboxes, and often the best candidate may have a different CV. Research from Harvard shows that women, in particular, tend to second-guess themselves and not apply—so if you’re hesitant, reach out anyway, and we’ll handle the worries.
