I recently moved to Seattle after completing a programming course to look for work. In the interim I started working at the gym near my apartment where I am a member.
When they hired me they asked if I was actively looking for another job. I said no because I wasn't really. I was putting in a pretty minimal effort after putting in a lot of effort with no results. So I was taking some time to work on my resume and develop some more skills.
However, my aunt asked for a copy of my resume so I obliged, which led to a phone interview at a large company. I feel pretty good about the interview, so I'm wondering what I should do about my current job. If it were any other stop-gap job, I would simply say something isn't working for me or my needs changed, but I like this gym and would like to continue as a member. The people here are friendly and supportive and I don't want to put them in a bind.
I have an in-person interview with the new company next week. If it results in an offer, what should I do to minimize any difficulties from leaving my current job so shortly after being hired? I was hired just over a month ago.
