Problem: What are Bona Fide Occupational Qualifications (BFOQs)? How can you find them? How do you describe a job after analyzing what that job is supposed to do? All of us 'smart people' think we can just figure it out when we need to, but then we realize that, even though we are really smart, there's just not enough time in the day to do everything that we should do.
Check out https://www.onetcenter.org/ and see if you can determine the job description for your current or past job. Did the description match what you were expected to do? What else is O*NET good for (I always enjoy the 'Skills Search' in O*Net Online)?
