I've had an interview and a case presentation. During the case presentation one of the people wasn't interested from the beginning on, on his phone the whole time and not paying attention. It felt disrespectful as I put a lot of time in the case presentation. After this I got an email that I made it to the next round. However, the next day the came back on this and said they didn't want me in the next round anymore. A very disappointing and unprofessional experience.
