You can't "network to get a job," it's impossible to do well, and it's a big turn-off to have someone get to know you and lose interest when you can't help them get a position at your company.
Networking is like farming. You plant seeds, cultivate and weed consistently, and harvest at the right time.
What you should do now is what you should always be doing. Things like:
- Have lunch with current or former colleagues several times a month.
- Attend at least one user group meeting every month.
- Speak at a user group meeting at least once a year.
Whether you are meeting someone new or someone you have known for years, focus on:
- What are they doing/learning that they are interested in?
- How can you help them to do their job or advance their skills?
Of course, you will be curious about how they can help you, but to have useful contacts, you need to be a useful contact, so focus on the part you can control.
Even though these are long-term strategies, start now. The relationships you develop during this job search may help you in the next one.
