Hi there,   This is kind of off-topic for this group, but hopefully some people can give me some advice. I've worked about 10 years in epidemiological research as a SAS programmer/analyst, but never clinical trials. I'm interviewing at a pharmaceutical company tomorrow for a statistical programmer position (seems like it's their entry level programming position) and I know they'll ask me technical questions.  Do you have any suggestions on what I should brush up on before the interview?    What kind of programming is involved? Is it all macros?  Are there any standard macro statements/functions/variables I should definitely know? Should I study up on SAS character and numeric functions? Any in particular that are used often?  Does everyone use SQL these days or can I do things in a data step?   I've googled a lot of clinical trial SAS programs and the macros look so unbelievably advanced. I'm afraid I might have psyched myself out for the interview tomorrow!  Thanks for any advice, I'd really love to transition to clinical trials and get some new skills! Jen  ... View more
