参考答案:B

【详解】
考查定语从句和状语从句的省略。句意：正如上面所提到的，那些缺乏工作经验的人在申请职位时很可能会被拒绝。分析句子可知，第一空处“____ is mentioned above”是定语从句，修饰后面整个句子，句子所述内容在定语从句中作主语，应用关系代词as引导该定语从句，且as is mentioned above为固定结构，意为“如上面所述”；在when, while, if, as if, though(或although), as, until, once, whether, unless, where等连词连接的状语从句中，常省略从句中跟主句一致的主语和be动词，第二空处“when ______ for a post”是省略后的时间状语从句，原句为“when they are applying for a post”，该句主语they与主句主语those一致，且含有be动词are，符合省略条件，省略they are后保留现在分词applying。故选B项。
