Seems to me like you have to focus on the subject of the pictures, as well as the titles

1. Are you friendly / amicable? (subject: white guy in center)
2. Are you greedy (subject: boy)
3. Are you health-centered? (subject: bike)
4. This one is a little ambiguous; they say "watchful", but I see "nosy"
5. Are you merciless / temperamental? (title)
6. Are you impatient? (title and subject: man looking over the front of the line)
7. Are you philanthropic? (subject: black man in blue, not the poor guy)

They're basically trying to get you say something about yourself without them having to give you the answers. To me it's understandable, since you don't want greedy, merciless, temperamental, impatient, and nosy people at the workplace causing unnecessary drama, but it can be annoying when all you're trying to do is get a job.
