The answer is YES. This is one additional opportunity for the hiring manager to get to know you and hear what you can bring to the role or the organization. This is the most personalized voice you will have in the beginning of the process- until you get to that interview.
J.T. O’Donnell gives the best career search advice and I love this new approach to cover letters. Storytelling- get good at it!
If you have some additional time on your hands right now thanks to a much-shortened commute, why not write a practice writing a cover letter and send it to a friend for input and feedback?
