Mudlogging interview questions

I filled out the online application and then recieved an email inviting me to have an in person interview. I went to Houston and talked with the human resources rep. Charles Becker. I was told over the phone that I pretty much had the job and that I just needed to show up for an interview and orientation. Orientation was later cancelled. I wasn't informed until I showed up. I financed the trip on my own dime and never recieved the job offer. This company recruits heavely and was a waste of my time and resources. They must have very high turn over because of the amount of recruiting that they do.
