IGT interview questions

had 4 interviews with the company - never heard back from anyone since - its been over a month and not a word - emailed the HR person I've been dealing with and not a peep - its fine if they don't want to hire me but at least be polite enough to follow up

Initial phone interview followed by a 1:1 interview with hiring manager. This was followed by an on site visit in Las Vegas, NV. Took almost three weeks to complete all interviews.
