For the past about month I have been doing a lot of applying to networking jobs. In the recent past there was a position opening within my company but I did not get the job

Anyway I kept applying but haven't had a ton of luck. So my Director approaches me yesterday and asks how I would like to start working with our Network Operations team maybe an hr or 2 a week to start building my skill sets. Naturally I accepted that with out even blinking. This would be a perfect opportunity to really get my feet wet with the technology and be able to put on my resume that I have some real networking experience.
Here's the kicker.
In my lye of looking for another job... A recruiter just calls me today asking to talk with me and he thinks I will be a great fit for a networking job coming up with a company, he had submitted me to the company and they wanted to schedule an interview. I figured what the heck, an interview never hurt anybody.
Well now I am in kind of in a toss up. I am trying to weigh what I should do should I get an offer with this place I am interviewing with. I really would only take it if it was a great deal, however I don't want to burn bridges and I feel like my director was really trying to look out for my best interest. I just don't know how well I will be immersed in with the small amount of time I am working with the network team at my current company and/or if that could even develop into a job.
Am I crazy for taking an interview / considering leaving if the gig ends up being great? My thoughts are I want to gain as much valuable experience as possible while I am still young.
Thoughts?
