ICU Medical Risk Engineer interview questions

Interview was setup nicely by the recruiter and confirmed. But when I got to the location for interview, i came to know that 2 of the of the interviewers were not aware that they were supposed to interview me. Then, there was no concession made to at least talk to me for 5 minutes if not all of 1/2 hour each as was allotted. How unprofessional. Then I was told to call them to schedule the rest of the interviews. I would not want to work with a team with that type of unprofessional attitude.
