Two hours skype interview, including SAS (PROC MEANS, PROC REPORT, PROC TABULATER, ect) description problems, and logistical, survival analysis, and how do you design experiments. Meanwhile, prepare some general questions, such as "why do you choose clinical research company" or "the difficulties you overcome".

Started with some general background questions, then a more senior employee drilled me on statistical topics and terms, and then a SAS programming challenge before a wrap-up with HR. Overall, everyone was friendly and helpful but I didn't get the sense that they really wanted to be there.
