the process took place over 4-5 different interviews. initial phone interviews, then an in-office interview for about 3 times. never took more than an hour and I interviewed with 3 different people

I applied through LinkedIn and received a call for an in person interview a week or so after. I came in for what was suppose to be a 30min interview but turned into a 3.5 hour interview, which I was ok with because I thought that that was a good sign. I spoke with three different people. After speaking with the three people, I was then invited to come in the following day at 8:30am to spend the entire day shadowing an executive recruiter. After shadowing, I was told to be expecting a final face time interview call from the highest up hiring manager two days later. I also was told that at that point, "all you need to be doing is thinking about if you seriously want to work for this company". LOL. So I finally spoke with the top hiring manager and thought it went pretty well. A week and a half passed and I had heard nothing so I decided to reach out with an email and was told that they decided to promote their administrative assistant. A recruiter reached out the next day and wanted to talk to me about another open position at Ajilon for a different but similar role so I thought surely enough this is it after ALL I've been through with this company. She rescheduled the first face time interview for personal reasons and we finally spoke after a couple of days of trying to reschedule. Again, a week went by and I heard nothing. I reached out and received an "Unfortunately we have decided to pursue other candidates" email. I found the whole process completely misleading, rude and wasted lots of time and energy.
