Rocket Windows Engineer interview questions

I applied online & updated the existing resume they had on file. In total I had 5 interviews with two different areas in their IT department over the course of almost 4 weeks. In one instance the recruiter sent out the wrong date/time for the interview & it was rescheduled. The 2nd time the team I was interviewing with was 15 minutes late & I had to contact the recruiter to remind them of the appointment. Once a few people joined the call the interview only lasted 15 minutes due to another meeting they had to attend. In short, it felt rushed & unprepared. I was not offered an onsite interview and suspect it was because I have a diverse background in different technologies & they required someone who specialized in specific areas. The recruiters were very nice, however the late/missed appointments make me wonder if this is part of a "too much on my plate" culture at Quicken Loans.
