There are many Career Aptitude Assessment tools, from free tests to paid, from specific theory-based to AI-driven, currently available in the market.
If you want to know the right tool, it's often tricky unless thorough research is done. Yet, finding an accurate test is even more difficult because results vary from test to test.
So how do we know a test is accurate?
The results are often a reflection of yourself, and the results should bring out your interests themselves. Certain times some strengths are highlighted, which you may not have noticed yet.
Also, as you upgrade yourself with skills and knowledge, the results would slightly shift, but a general trend would remain. Career tests can be thus considered an assurance for the decisions you have made for yourself or as a direction indicator if you cannot decide for yourself.
The results, however, need to be continuously compared with the job market relevance and should be compact with your particular constraints, if any.
Talking to people with exposure in specific fields will help you understand the course you may want to take. Platforms like Quora can be used to ask questions.
However, taking help from a career guide will give new perspectives as they would have gone through many such cases and can share with you related decisions made.
Best Wishes for a bright future!
