Liberty Mutual Insurance Underwriting Assistant interview questions

The recruiters need better communication with the candidate and the interviewer. I missed out on an interview because the company recruiter failed to give me the name of the interviewer(s) when I requested it in a timely manner and went on vacation. I thought it was strange, since the recruiter email said I was confirmed for that time. When I asked who I would be seeing, she said she would need to get it confirmed and let me know. I replied thanks, and I please send me the information. No reply. I emailed her again and nothing. I finally called and that is when the out of office voice message came on saying she was on vacation and to contact the general email address. I did, but no reply. I tried again the day of the interview but no reply. I thought that they were not interested anymore. I got a call (voicemail) from the interview asking me if there was a miscommunication and if I was still interested. I was driving at the time and couldn't call back. I replied within the hour and got his voicemail. I left a nice message explaining the situation and that I was still interested. I also emailed him. I followed again with the general email box and they said they apologized for the delay and that I didn't get the information. Nothing about an interview. I then emailed the interviewer, who said he was not ignoring me, but trying to figure out what happened. Within the hour, I got a call form the original recruiter saying they went with someone else, apologized, and also said that my email address used on to register on the company site was different than my resume. I told them that my email had my name and email address to use, and my cell number, and at no time before did the recruiter mention anything about my email address being different on my resume from the registration.
