There are two possible cases for which a candidate may not be able to independently schedule the first online interview, once the candidate has received the invitation email from Lionard.
First: it could be more than 72 hours after receiving the invitation, which is the time limit for fixing the appointment.
Second: in the agenda of the recruiter who is in charge of the examination of that candidate, all the spaces dedicated to the selection could be occupied. In the latter case, we recommend that you contact the HR recruiter at the references contained in the email invitation received. By explaining the situation, it will be possible to request the availability for another time slot.
