My answer to How do I know if someone is the right candidate for startup in very early stage?
Answer by Ken Larson:
Startups rely on versatile, creative individuals who can contribute, not only in their career specialty, but also in on a broader basis in terms of how their job relates to the company as whole.
Stove-piped thinking and individuals that require and expect a great deal of company support for functions not directly related to their job do not belong in a startup.
Write a job description for the candidate(s). Write it in such a way that the expectations for performers include working on a global basis within the company to create the whole enterprise as well as their function within it. Then describe the specific function.
Give the candidate the job description and a half hour to write what they can bring to the position and the scope of the job.
Assess the communicative skills of the individual in conveying in writing and verbally what they can contribute and their expectations in return.
Make the hiring decision and set the salary based on the results of the above.
