HR's respond was good. They provided useful information. Send invitation email and confirmation. The interview was about one hour long. There was some board discussions. The manager was friendly & polite. The questions were reasonable. Nothing tricky. They seek to understand the skill and experience of the candidates.

telephone interview, then in-person interview (4 - 6 hours), starting with me presenting a 45 minute "technical presentation". Directions on the presentation were vague and inadequate. Feedback was the presentation should be about your job history - what you did, how you did it, and what was the result.
