Lakeside Behavioral Health System interview questions

I applied for the position online. After 2 days, the Chef called for an interview. He came with my resume in hand and went over my experience. He said that he would turn my name into HR and I would be receiving an offer. HR called and presented me with an offer, if I passed a drug test. Orientation was scheduled for late December 2024. HR called me and let me know that since they hadn't received my drug test results in time, my orientation would begin on January 13, 2025. Before that date, I was under the impression that HR would phone me and give me the specifics of the orientation, but they never called.
