"The hot seat" is a common idiom used to describe a situation in which someone is put under intense scrutiny or pressure. However, there are several other phrases that can be used interchangeably to convey a similar meaning. For instance, some people may describe this situation as being put "on the spot" or being "under the microscope". Others may use the term "grilling" to describe a similar situation where someone is being questioned relentlessly. Alternatively, some people may describe this situation as being in the "crosshairs" or being "in the firing line". Regardless of the term used, all of these phrases convey a sense of intense pressure and scrutiny.
