Good hiring techniques
I recently read an interesting tweet - OP posted, to screen through thousands of applications (remote executive assistant, for example), he would make them do an online writing speed test. The hypothesis is that: 1, some large % of people will not follow the instructions (critical for an EA), and 2, people with a high word count/accuracy score are more likely to be intelligent and articulate, despite it being likely that english is a second language (remember OP is posting for remote EAs).
I'm curious what other similar hacks people have come across to quickly screen through large pools of applicants.
