Don't bother - they only interview external candidates to show their due diligence when they already have an internal candidate selected. They are quite responsive and helpful to get you the interview - then radio silence and not even a token "thanks..." email when you don't get the job. This has happened with multiple jobs at the company - extremely horrible experience for a candidate to put them through the process even when they have someone identified. Completely uncaring, phony, and fraudulent process.
