Stephanie Said:

How do you sign your cover letter if you are emailing it?

We Answered:

You don't need to sign it, but I sign alot of documents electronically with Adobe Acrobat.

Honestly, as someone who sees alot of resumes, I wouldn't care at all. In fact, I might see the signature as unnecessary and overdoing it, depending on my mood.

Keep your focus on the fundamentals: follow up call to confirm they recieved it and ask for appointment, do research on the company, be prepared for standard interview questions, send thank you emails to everyone you meet with, etc.

Go for it, and Good luck!
