This chapter revolves around the interactional uptake of age categories and the predicates that are sometimes associated with them. More specifically, we investigate challenges of the use of age categories as well as extensive negotiations of age and category-bound features and activities related to them. While there are some recurringly constructed links, such as between the category ‘young’ and the feature ‘inexperienced’, other links are far more idiosyncratic. Moreover, we show that the evolving nature of conversations presents many opportunities for candidates and recruiters to negotiate such categories through the dynamic process of associating categories with specific attributes or actions. In this fluid environment, we demonstrate that interlocutors may not only introduce new elements, but we also tease out how existing categories and related predicates can take on new significance. Overall, this chapter highlights especially that the invocation of categories and category-bound features and activities is an in situ accomplishment.
