You haven't seen the ad, and in the OP, I mention that it includes a full job description. So there's that. Bear in mind, this isn't the interview stage yet, this is merely the screening stage. As of about ten minutes ago, I have fifteen solid candidates and seven or eight that are marginal.

As for the required KSA's, the first is that they need to know how to write a professional letter. When the cover letter looks like it should have been written in crayon, that's a fault. The job requires attention to detail. What does that look like on the job?

• It means sending letters with confidential information to the right person. When they address their resumes and cover letters to the wrong people, that's a problem, potentially a huge problem.
• It means making sure the details are correct. Sending a report that indicates test scores of 70 when they should be 40 can result in unnecessary tests/treatments, delays of treatments, referral to the wrong clinics, etc.

Someone who reuses their friend's resume but doesn't bother changing the name in the heading on page 2 doesn't have attention to detail. They also clearly don't check over their work, which is a huge problem.

Give me a person who can write and knows how to conduct themselves professionally, and we can teach them how to do the job. We're not requiring experience, just decent writing and some common sense. The on-the-job mentoring is intended to teach the candidate how to write a letter specific to the situation. We provide a lot of training, but we need a candidate with basic skills.
