Got called in for an interview on Monday

Investigate the tasks required of the position, ask questions and translate your current skills to that position.

You're nervous but that's okay. Just be attentive and inquisitive. They've called you since you seem like a likely candidate. I had similar worries coming out of retail but, assuming you were reliable in the past, you look like a stable employee. Just be willing to learn and adapt your skills.

Here's what all employers want: reliability, honesty and accuracy - as well as someone who can think and act independently when needed. Use these attributes and dig out life experiences that demonstrate such things. Chill.
