I received an e-mail for the opportunity for an skype interview. In the e-mail it said I had to prepare a case study and attached were some information about it. It also mentioned in the e-mail that the interview was going to be around one hour long. But turns out it was only an assessment based on the case study I had to present. It has been months and I haven't heard back. I even wrote an e-mail asking for an update and nothing.
