Started a new job with great opportunities but my manager has an attitude problem. What to do?

I’ve been unemployed for a couple months so it’s fortunate starting in the medical/office work field. However, my manager is a late 20s to early 30s year old woman with an attitude problem. It’s obvious they made her manager just from being there the longest and understaffing.

I’m still in training so whenever I ask a question she rolls her eyes, sighs, mumbles under her breath, and speeds through her “explanations” to run off leaving me still dumbfounded. Then when I’m expected to do my job, she points out every minor issue of my work due to her lack of leadership.

I got hired through HR but have been unable to contact them. Now, I’m on my third week and I feel like if I don’t straighten up then I’ll be getting the “it’s not working out” conversation.
