Pindrop Fraud Analyst interview questions

Started with one phone interview with who I would assume to be the hiring manager, then moved on to 4 other phone interviews with people of various jobs within the company. (At this point had communicated with 6 different people in the company, not one person more than once). Was told I would hear back in the following week. Heard back from a different HR person asking for a time to chat on the phone that same day, responded within an hour, and no response from that HR individual. Now over a week later, have yet to hear anything back. Seems very unorganized and very odd to me to do 5 phone interviews before an in-person interview. Upset at the amount of time I have put in to this company already, only for the same regard not to be extended out to me.
