I've recently received the task to coordinate and perform a job interview for an internship position at our company. I've no experience at all at this, so please excuse my (maybe stupid) question.
So far, the whole application process of the candidate has been in German (native tongue), but for the interview I will be supported by a colleague who does not speak German. Therefore, I will conduct the interview in English.
Should I inform the candidate about this or is this something a candidate has to expect when applying to an international company? English skills are a requirement and clearly stated in the job description.
