You are right in pointing out the asymmetric nature of job interviews, namely "You may want to work for this person" vs "You may want to hire this person".
In the current model we wanted to keep things simple and leave as much as possible to them to decide or know. With a check box, we may ask them to select exactly what they want with this particular person.
Do you think, for every selection, asking whether you want to hire or you want to work for a particular person is really necessary, or is it enough to leave this to them, of course with a certain risk of misunderstanding in some cases. I would be pleased to hear your opinion.
