The most important thing I learned in this course is the predictive power of cognitive ability in employee selection and the value of using assessments like the Criteria Cognitive Aptitude Test (CCAT) early in the hiring process. This stood out to me because it directly challenges a flawed but common hiring practice I’ve seen repeatedly—making hiring decisions primarily based on whether someone “feels right” in an interview.
I’ve participated in multiple hiring discussions where other decision-makers focused almost exclusively on whether they liked the candidate. While likability and cultural fit are important, relying solely on gut feeling or how well someone performs in a loosely structured interview is a recipe for inconsistency and bias. This course helped me understand why that approach often fails: interviews, particularly unstructured ones, are not the most valid predictors of job performance. In contrast, cognitive ability testing has one of the strongest correlations with job success, especially when combined with structured interviews and work sample tests.
Learning about tools like the CCAT helped me rethink what it means to build a fair, effective hiring system. The CCAT doesn’t just test intelligence—it measures problem-solving ability, adaptability, and learning potential, which are all essential in fast-paced, cognitively demanding roles like the ones I’ve hired for in the past. Pairing a cognitive test with a situational judgment test (SJT) or personality inventory also helps triangulate key traits like conscientiousness and emotional stability—qualities that significantly impact long-term performance and retention.
This lesson matters to my future career because I plan to take on leadership roles where I’ll be responsible for building teams. Being able to explain—and implement—a structured, evidence-based selection process will help me avoid bad hires, reduce turnover, and promote equity. It also positions me to advocate for tools and methods that may feel unfamiliar to others but are proven by research to work better than intuition alone.
In short, this course gave me a practical, research-backed framework for talent selection. Moving forward, I won’t rely on who seems most charismatic in an interview. I’ll rely on structured tools that actually predict success.

Hey Samuel, thank you for sharing! This is such a solid takeaway. I completely agree that relying on gut feeling during interviews can lead to bias, and it’s eye-opening to learn how much more effective structured tools like the CCAT can be. I also like how you connected it to future leadership, having that framework will definitely make a difference when building strong, fair teams. Nice work on the post.
I really like your point about the importance of using cognitive ability tests like the CCAT in the hiring process. It’s so easy to fall into the trap of making decisions based on “gut feeling” or likability, but as you pointed out, that’s often inconsistent and biased. Cognitive tests give a much clearer picture of a candidate’s potential, especially when combined with structured interviews and other assessments. I think your approach to talent selection will really help reduce turnover and make more informed, fair decisions in the future. It’s great to see you focusing on evidence-based methods over intuition!
Hi Samuel! Your explanation of the importance of performance tests in recruiting and selection gave me a new perspective. While I initially thought of them as annoying and irrelevant, you changed my mind. Previously, I’ve taken one performance test as a sort of pre-req to an interview. In the moment it seemed silly for the employer to need to know how many words per minute I could type and whether I could tell which shapes were the same. But your explanation made me realize it’s more so to ensure the competency of an applicant. While I think this specific test was not the most valued part of the hiring process, it gave them some background to go off of.
