发帖数: 772 | 1 等了好久终于有个On-site了，是一个朋友废了好大劲一直帮忙才得到的机会。
想好好把握，有在SAS PROGRAMER的网站上看INTERVIEW QUESITON。
除此之外还有什么东西需要搞得特别懂吗？如果现在要CODE一般考什么？是MERGE DATA
,PROC FREQ, PROC UNIVARIATE, PROC GRAPH这些？
还会问那些理论吗？比如PDV？
还有这个公司是个CRO，我没有CLINICAL的DATA ANALYSIS经验，我也直接在电面里很明
确地说了，朋友说经理好办，但是BOSS很PICKY特别是对男生。
求帮助！ | s*********r
