Police subjected him to hours of questioning.
警方对他进行了数小时的盘问。
变成被动语态则是：

他被盘问数小时/他受到了数小时的盘问。

be subject to和be subjcted to都可以用，两者的细微差别是：be subject to指”面试者必须(MUST)经过详细审核“，subject的形容词特性更多是描述一种条件或状态；而用be subjected to强调求职者是集中面试、背景调查以及评估的”直接承受者“(或带有HAVE TO的感觉)，subject的动词特性更多是强调动作。
总结：两者有时候可以互换，但有一些细微的差别(如上分析)。be subject to中更多是描述一种规定、条件、情形、状况；而描述”不情愿、被迫的经历“更常用be subjected to的结构。
