Spectrum interview questions

I had an initial phone call with local manager and then HR stepped in to move the process forward (which was bit strange). I had 2nd interview in-person with another manager which was cut short (total interview time of 15 minutes even though it took me an hour to travel to her temporary office because she was traveling) since she didn't have the office for set time. It went ok (it seemed they weren't very digital-savvy especially for this role even though they advertise digital offerings on their site). Next time I heard back was 2 weeks later from another manager for phone interview. After multiple follow ups and waiting, HR relayed it was between myself and another person - I was under impression that I would secure this role as HR kept insisting the team was impressed by me and "excited" for me. After initial contact, 2 months later I got call I didn't get the offer. Fine. But don't see how it took 2 months to finally give an answer after chasing them down for a final answer.
