I had one interview and then I was asked to complete a written task. There was no further interview in the process. Was then contacted via email. Fair interview process and the interviewer was very nice.

Very much contingent on your previous work and portfolio. If you've been writing on beauty-related topics elsewhere, and are able to talk about this, the interview is more a test of interpersonal skills, conscientiousness, etc. However, if you haven't been writing publicly elsewhere, you're likely to find it a bit of an uphill task not having any work to refer back to.
