Frequently asked questions

How long should a job description be?

Long enough to list the responsibilities, required and preferred skills, tools and logistics, usually 300 to 500 words.

Should I list a rate in the description?

If the client allows it, a range helps candidates self-select. Otherwise state it as “rate to be discussed” and confirm it before submitting.
