Block PCB Layout Engineer interview questions

There were two parts to the interview. I interviewed initially over the phone which was great. I felt I had a great repertoire with the interviewer. However, when I went to go for my onsite interview, it was supposed to be an all day interview. However, after being interviewed by the first person, they told me to go home. I did not understand and was totally confused. I felt humiliated and my time was entirely wasted as I had to drive from the south bay to SF. I found the entire situation entirely unprofessional.
