Coworker keeps engaging me but I can’t tell if it’s just friendliness or something more. How to tell if she likes me ?

I’m probably overthinking this, so I wanted an outside perspective.

I work at a bank and I’m about to rejoin a team I was already part of before (I was on a temporary assignment elsewhere). So I’m not new to the role, even though some of the people around me are newer hires. Our VP even pointed that out in a meeting, saying me and one other girl aren’t really “new” like the others.

There’s this girl on the team who originally worked as a teller in-branch. I actually met her once months ago (in September) when she served me, we had a quick conversation about my background and the fact that she had spent time in my parents country (she went to high school there). Didn’t think much of it at the time.

Fast forward to now, she joined my department. A couple weeks in, she recognized me in a meeting and called it out when we were all leaving. Since then, she’s been the one initiating pretty much all interactions.

Some examples:

• She’s come up to me when she’s with other coworkers and started talking to me specifically
• One time she literally left the person she was walking with just to come ask me a question and we walked back together while talking
• She asks me work-related questions but sometimes adds things like “is it normal to feel like I don’t get this stuff sometimes?”
• She’s invited me to join for things like grabbing food with the group
• She generally seems more engaged with me than I notice her being with other guys (at least from what I’ve seen)

At the same time, it’s not flirty at all. No giggling, no obvious signals. It’s calm, focused, and pretty normal on the surface.

On my end, I haven’t really reciprocated much. I’ve been more reserved lately, mostly just answering her questions and keeping to myself. So if anything, she’s put in more effort interaction-wise than I have.

Part of me thinks:
“ok, she might be a bit interested or at least more engaged with me than others”

But another part of me thinks:
“she’s just new, being social, and I’m reading into normal behavior”

Also worth noting, she does talk to other coworkers too but when I overhear its not as energetic compared to when its with me, so I don’t want to assume I’m special here.

So I’m curious what people think:

Am I overanalyzing normal coworker friendliness, or does this sound like she’s at least somewhat more interested/engaged with me than average?

And if it’s somewhere in the middle, how would you even tell the difference in a workplace setting like this?
