When you've found a few people who you'd like to keep track of stick them in a Talent Pool.
This allows you to invite them all to an opportunity in one go and just sort through the ones you like quicker.
The fun part is that you can keep this Talent Pool all to yourself or make it visible to other Hiring Managers who are also looking for the same sorts of skills.
Rather than searching for a needle in a haystack, keep all of your needles neatly organised and easily accessible.
You can organise by your favourites, a particular skill or even people whose preferred work location match up to that new office you've been tasked with recruiting for.
