It doesn’t matter if you are working in the cafeteria or the inspection line of a plant, companies will now only hire people who can see problems and organize responses. 问下这个句子的结构怎么分析？是逗号连接两个句子吗？感谢回答。
逗号隔开的是两个独立的句子，前句主干是It doesn't matter为主谓结构，其中it充当形式主语 matter为谓语，if为连词引导条件状语从句，后句主干是companies hire people为主谓宾结构，who为关系代词引导定语从句，先行词为people在定语从句中充当主语。前后两句主语分别为it和companies，如果前后主语一样可以将前句主语省略改为独立结构。
