I applied online and was contacted by HR a couple days later. I had a phone screen with the HR rep, then a phone interview with the hiring manager, then a series of in-person interviews with 5 people from the office I would have been working in. I also had a 45 minute-long writing test. Everything was very positive up until this point and people were very friendly. However, it has now been over three weeks with no response to my follow up email(s) and no updates on the decision process. I assume they've filled the position, but I would expect a large professional company who facilitated such a personable interview process to at least send a template rejection email when I had invested that much time into their company.
