It is the theory that women are less confident than men. As a career coach, I can honestly say that I see it with clients. Men are innately more confident about their abilities, skillset and perception of themselves.
An example I use is a man and a woman will look at a job posting and the man says they have at least 5 out of 10 of the requirements and they don't hesitate to apply for the position. The woman looks at the same job posting and says I have 7 out of 10 but I don't think I should apply because I don't meet all the requirements.
As a career coach, one of the areas that I work with many of my clients on is self-confidence. Lack of self-confidence can be something that the client has always felt or it can be situational. They may get blindsided by a layoff or experience a change in organizational structure which results in being let go or feeling like they are constantly being challenged.
I enjoy working with all my clients but I especially love working with women because as I get to know them, see their accomplishments, hear them talk about their experiences. It is very clear that they have what it takes to succeed. My programs work because they are set up to be a process and that process works on rebuilding or gaining confidence.
The best part of my day is when I get that call and my client says, "I got the job offer." Priceless!! Every time!!
