About CareerFitter
A career assessment and guidance platform helping people understand their work personality, natural strengths, and the career paths where they're most likely to thrive.

Who We Are
CareerFitter.com is a career assessment and career guidance platform that helps people understand their work personality, natural strengths, preferred work environment, and career options.
CareerFitter.com went live in 1999. Since then, CareerFitter has helped millions of people explore careers that better align with how they think, work, communicate, make decisions, and thrive professionally.
CareerFitter has been used by students, professionals, career coaches, psychologists, government organizations, universities, and companies around the world. Its purpose is to help people make more informed career decisions by understanding the kind of work and workplace environment that fits them best.
Expert Involvement
CareerFitter's development has included contributions from professionals with backgrounds in human resources, psychology, psychological consulting, performance consulting, clinical psychology, career research, workplace development, and performance psychology.
Steven Hecht began his career as a human resources specialist for a large accounting firm. Recognizing patterns between personality and job fit, he completed his degree in psychology and moved into psychological and performance consulting. He authored the book Career Fitter, (no longer in print) which was adapted online to become the foundation for the initial assessment for CareerFitter's first career test, the work personality assessment. Hecht originally incorporated some of Carl Jung's research on psychological types with specific focus on career matching and work personality traits. Hecht contributed to research and development from 1998 through 2010, including the 1998 disparate impact study. Later in his career, he became sought after as a psychological performance coach for professional sports teams.
CareerFitter engaged a doctoral-level psychologist — a graduate of the California School of Psychology with over 20 years of clinical experience — to provide contracted consultation and content review. This work strengthened the assessment's psychological framing, clinical language accuracy, and content standards across the platform through 2023.
Dr. Will Cunningham contributes to CareerFitter's ongoing research adaptation and development. His background includes counseling, coaching, positive psychology, wellness and performance psychology, and strength-focused development. He also brings experience in leadership, trust-building, conflict resolution, and decision-making developed through intelligence operations and military-support environments. His ongoing contributions help CareerFitter adapt its assessment and career guidance content for modern users, focusing on practical career insight, personal strengths, and meaningful work alignment.
Our Assessment Approach
CareerFitter focuses on work personality — also known as professional personality. Instead of treating personality as a general label, CareerFitter looks at how personality traits show up specifically at work.
The assessment evaluates four core dimensions of how you work:
In 2022, CareerFitter introduced its proprietary Aptitude Aversion Assessment (A3), adding another layer of insight by helping users identify not only their strengths and interests, but also the types of tasks and work patterns they may naturally resist. Together, these tools help users compare their personality, preferences, aptitudes, and aversions against the requirements of over 1,000 careers.
CareerFitter's mission is to help people discover who they are at work and identify the careers and work environments where their personality can thrive.
We believe better career decisions come from better self-understanding. By helping people understand their work personality, natural strengths, preferred environment, and career options, CareerFitter helps users make more confident decisions about their future.
Since 2025, CareerFitter has been expanding with AI-powered career tools built directly on each user's assessment results, including personality comparison analysis, customized career resume enhancement, and advanced career matching, bringing a new layer of personalized intelligence to the career guidance experience.
