It’s important to consider how you develop that first impression. For example, if the director from your desired company will be speaking soon at an event, it’d be more impressive if you establish a connection there. Or maybe they recently posted an article or you read an interview of them that really spoke to you.
Basically, you want to be careful about having people remember you as “that guy who’s looking for a job.” Find some common ground to help create connections with others and then work from there… or have a friend do the connecting for you.
