I can't do nothing more than a warning to you guys in case you are applying for any position in this company. Only warning I can give is that they are highly unprofessional with this kind of actions, I can't even imagine what kind of actions they do from the inside when you are working for them.
Just needed to rant about this because this was the first interview I needed to have after losing my job. Fully prepared for it and put everything else on hold.
