1) Speak a language of attention
Attention isn't just one thing. It's now considered by most neuroscientists to be a tripartite set of skills made up of focus, awareness, and executive attention, i.e. planning and decision-making.
Perhaps most importantly, scientists are beginning to discover that attention can be bolstered through practice and training. There's more research yet to be done on this score, but these initial discoveries can help us thrive in a world of overload. Try deliberately using all your senses to expand your awareness fully when you're in a new situation, such as a job interview.
