G.C.P. interview questions

I sat for a first interview. It was interesting, no cliché questions. There were a few tests none of them was that difficult, then I was invited for a second interview where I sat for more tests then I was asked to go to another room where I discussed my test answers with the interviewer and was asked about my education and experience but this time in more detail than the first interview. They offered me the job by the end of the interview.
