NiSource Senior Financial Analyst interview questions

I have nicknamed them NoSource. Had a phone screen with HR. Basic questions, but was also asked what questions I had about the company. Heard back next day and was offered an on-site interview. It was a group interview with hiring manager, senior manager, and HR contact. Questions were pretty basic and followed STAR format. Then had interview with director and HR contact stayed. After interview, followed up with HR contact several times to check on status. Was given very vague responses, but was never told I was no longer in consideration. Notified them I had another offer on the table and got dead air...

Multiple interviews with 8-10 people including one senior executive.
