first job interview

Fa

so, I've been staying at home with baby since I've had him (5 months.) And my SO told me he needed some help with bills, so I would need to go back to work. I got a call this morning for an interview at 9 am on Friday. Thing is, I graduated college and got pregnant right after, so I didn't get to work in my field yet. it's been a year since I've graduated and feel like I've forgotten everything. It's for a resource pool position. Any tips for interview or leaving my baby??
