Lockton Companies interview questions

At first I was impressed. I applied on line, the next day HR reached out to see if I could do a phone interview with a Unit Manager. The phone interview went well so a week or so later a 4 hour interview was set up. I was to meet 5 people including the Director of Talent. I also was going to be evaluated in a role play where I was to see how I handled an irritated client. I was also going to be evaluated on my Excel skills and see how well I could extract information from a benefits booklet. I saw my scores and I was near perfect on both tests, and the interviewer told me I did really well in the role playing exercise. After meeting with the first two interviewers, I was told the third person was sick, so I sat in room to wait for interviewers 4 and 5. I heard the 4th person's name read over the overhead paging system twice. Then 15 minutes later, I heard the 5th person's name being paged twice. After waiting 30 minutes, the original interviewer told me the others had a scheduling conflicts and that I could go home. I only met with 2 of the 5 people I was suppose to meet with. I reached out to the Lockton recruiter the next day to find out what happened. I also reached out to the others and either thanked them, or asked if we could try to meet again. No response, no apology, no explanation. I am disappointed in how they handle things. Unprofessional.
