Whilst Skills are normally used for talent pooling between candidates and vacancies, they can also be a powerful tool for finding the right candidates to work in specific companies or departments. You can then go a step further and use them to find candidates with the skill sets that would suit specific hiring managers or contacts, based on your knowledge of them looking for that skill set.
To do this, you would assign the skills directly to the company or contact record, which can be done form the skills tab. You can then use the groups to find the right skill before clicking to add. Alternatively, the quick select will allow you to type search the name of the skill before adding to the record.
Hint - Once skilled up, you can use query builders to search for records that have the skill sets you need, which can be useful if you work in a candidate driven market, trying to find the company or department that is the best fit for that candidate.
