Networking is still the truest, time-tested approach to landing a job. Whether it's company outings, social gatherings, or sports activities, the summer months afford you a range of events to meet and interact with executives in less structured environments. The superheated economy also lends itself to summer job searches. While this creates uncertainty for some employees, it can also be an advantageous time to explore the wealth of new opportunities that are being created in these fast-changing times. Father's Day, Fourth of July, Labor Day, even weddings and barbecues can present situations to meet and network.
Exposure is the key here.
Try to find out who will be at the party ahead of time. By doing this you can target specific people you want to meet. If you're in the market, tag along to a friend's company outing. Most companies will also invite clients or customers to their parties. Strike up a conversation with the CEO of a company that does business with your own, but be very discreet.
