Essentially a Machine Learning project where you’d take data from a huge public database of people with faces and professions. Then study whether there’s any correlation between having certain facial features and the profession you’re in. Maybe use results to create a tool that predicts how good a fit a person will be for a particular profession, given just their face. Perhaps this tool would give better results than random.

Why might there be a correlation in the first place? Certain Facial structure may make you a better fit for one kind of job than another (if you have better-looking jaws you’re more likely to get customer service roles, if you wear glasses you’re more likely in a tech role etc). Also, your job may require certain kinds of reactions more often than others (for example, if you’re in customer service, you probably smile more often than frown which shapes your muscles accordingly). There’s more possible reasoning here: https://chat.openai.com/share/3013a6e3-096f-463f-9413-11ae53d07cdd

It could totally happen that there is no correlation, but this seems promising enough to be worth investigating.
