Giant Magellan Telescope interview questions

First step they make contact with the candidate (phone screening) and they make a phone interview with the owner of the position, after this you dont receive any feedback or comments, second interview takes around 2 months ( a little unprofessional) face to face interview is a power point presentation according to their guidelines about your experience or field, and diferent departments are present to make questions and listend your presentation (VERY UNPROFESSIONAL ) some of the participants dont pay attention, look for stuff on their phones and at least one of them was sleep during 90% of the time.
