Following up after interview

January 7, 2014 forum topics
I had two jobs interviews right after Christmas. Both positions I’d love to have, both are in areas I really want to go to, plus the job’s are what I’m seeking.

One position I interviewed at on Dec 26th (in person), the other on Dec 30th (via phone). I sent thank you letters after my interviews. Due to New Years during the week, I called both places as follow-ups after, but haven’t heard anything yet. I don’t want to be annoying, but be persistent, since these positions are what I’m seeking. I haven’t heard back yet from either, so am wondering the frequency of my follow-ups ???

The hiring manager both know I’m very interested, but wondering when I should call next ?
