Do you think that interpreters should be allowed to go into interviews?

An implied requirement for employment is that the applicant be able to commnicate to others and understand what is said to them. If a person is unable to understand the language and requires an interpretor, that person doesn't qualify for the position. This isn't discrimination. It's practicality and sometimes a matter of safety. I have someone like this at my place of employment - can't understand and can't be understood. Always misunderstands and gets angry. Doesn't want to understand. We DO have to use an interpretor and this isn't always comvenient nor possible. The only reason this person is still employed is because they've been there for so long. It's a "mercy" job.
