Continental Internship, Software Developer interview questions

Got a phone call out of the blue a month after applying saying they would like to set up an interview next week. Set up a video interview with one of the engineers through H.R. It was a very casual interview with most of the questions being about my experience level. By the end of that week they told me that i had got the internship. The following month and a half was going back and forth with H.R. to do a drug test and fill out forms.
