I applied for an offer of receptionist on Sunday and was contacted on Monday saying that it is a 2 weeks contract for July and if available we extend the month of August and then a cdi . I leave my current position on Tuesday for this position which corresponds more to my expectations and so arriving Thursday at the workplace I explain that I am the replacement of a colleague on leave. But I am informed that this post has already been provided I tell them that cityone contacted me I signed my contract. Then we get information from the rh of my company actually someone had already taken this position. The information had not circulated between people in cityone it. Inadmissible I found myself without work! A tip: do not work with them especially now that they do not respond to my messages, mail and phone! But also there was no CDI!
