Is this woman interested in me?

‌
I met someone at my new job after switching companies about six months ago, and I'm getting a strange vibe from her.
Actually, we are in different departments, so we only exchange greetings once or twice a day, but she talks to me every time she sees me.
She starts small talk like "How is your day?" or "What are you having for lunch?" and keeps the conversation going.
Since we mostly just run into each other once or twice a day while I'm moving around, I usually just give short answers and pass by,
but she keeps talking to me.
Up to this point, I thought I might be overthinking it, but
there are a few other things I've noticed:
1. Aside from constantly bringing me snacks, she keeps looking after me with all these little things.
2. I'm not sure how she got my KakaoTalk (she probably added me from the group chat), but she reaches out to me privately on KakaoTalk.
She asks things like "What's your profile picture?" "Where was that taken?" or "What's your MBTI?"
She asked if I'd seen Odyssey, and when I said no, she replied, "I haven't seen it either!"—conversations like that...
It's not like we talk every day, but she reaches out out of the blue once or twice a week like that.
3. I'm on the thin side, and she keeps saying, "Why do you always eat things that don't help you gain weight?" and "I need to help you gain some weight."
So I said, "Let's eat something delicious at the next company dinner~"
And she replied, "Oh, I missed the part about the company dinner, so I thought you were asking me out to eat just the two of us!!" while sending heart-fluttering emojis...
4. Most decisively, other employees are making comments like this.
For example, her senior colleague said to me, "She's pretty, right?? But she says she's still single," or "She said she's never seen anyone as handsome as [My Name] before."
Something like that?
At this point, is it safe to say she's interested in me...
