The company called to confirm my interest and availability for an interview. I agreed to a session, and they told me that they will send me a confirmation email / official email. Until the day of the interview, I received nothing. I dont even know what to prepare for, when the interview will be held, where the interview will be held etc. Seems like they're not professional and either forgot about me, or decided they were no longer interested in me after calling me the first time.
