Did I come on too strong too fast?

Met this girl at work as I moved to a new position. I spent a total of 4 shifts over the course of 2 weeks training under her which basically has the two of us alone in a little office and the work load is really light so there’s not much to do but tap a few buttons on a screen and talk for 5 hours.

Now here’s my issue. At first the conversations were light, just getting to know each other’s backgrounds, hobbies, blah blah. Eventually we started talking about deeper things like our social anxieties. Ended up getting her number on our second shift and texted maybe once or twice max. I thought things were going well so on the day of the fourth shift I asked if she wanted to grab some food before work but she was busy watching a judo competition which she mentioned before that she was into so I just said “all good some other time then”. After that fourth shift she was scheduled to transfer to a new location the next week so I figured I had to shoot my shot before she was gone for good so I told her I really liked talking to her and tried asking her if she wanted to hang out but got interrupted by a co-worker walking up ( talk about bad timing bro). Anyway, I texted her later that week about random stuff and she asked me if I work that week as well and it ended up I was only scheduled one day with her and she said she was sad about it. I told her that doesn’t have to be the last time we see each other and asked her if she was free for lunch over text. She said I’ll let you know but that was about a week ago and she hasn’t said anything.

Well her transfer got delayed and so now I’m still seeing her at work and things feel awkward around her. She keeps looking at me and I keep looking at her. It feels like we’re total strangers again and I’m getting hella nervous and I can’t bring myself to go up to her to chat. I’m just wondering if I moved things too quickly or came on too strong.
