Bunker Hills Golf Club interview questions

I was under the impression I was being hired for the job after shaking hands with the hiring manager concluding our interview. I waited two days for the onboarding info I was told to expect. However, on the second day I received a notification that the position had been filled. I wasn't sure if this was an error on their end or if I didn't get the position after all. Multiple calls and emails yielded no response.
