The job interview is a two-way street: the employer learns more about the applicant and, especially in the case of international recruitment, the applicant learns more about the employer.
Interview practices may vary considerably from country to country. In addition to informing the candidate in advance of the time and place of the interview, it is a good idea to share with them its estimated duration and main topics. Attach this information already to the interview invitation.
If possible, more than one representative of the employer should participate in the interview. People pay attention to different things, and one representative can take notes while the other is speaking.
If there are multiple interview rounds, it makes sense to use a remote connection for the first round in international recruitment. Second-round interviews deserve in-person meetings.
Ask for references and recommendations. In many countries, references are given in writing.
