Some suggestions (desperate pleas, even)
* A way to see all replies to your own comments or posts * Setting defaults for sorting rather than having to manually sort by recent every time * Put the see all comments link in a reasonably easy to find place * "All posts" which actually shows all posts...
Good luck not getting a disparate impact suit if you try this. You have to prove that the test that you're using is necessary for the job. College is basically always considered necessary. The coding interviews you mention are obviously necessary. Trying to use an IQ-like test or even the SAT (unless you're a college) will get you in court.
