Good follow-up and coordination by the Oracle recruiter. The interview was set up very quickly with the hiring manager after the initial contact.

The interview with the hiring manager was one of the worst interview experiences I've had in more than 20 years. Initially, she just talked about her department and their responsibilities. I threw out a few questions along the way to get more information. She seemed more interested in hearing herself talk than really conveying the importance of the job.

Later came the technical questions, and admittedly, I knew some and others I did not. This went on for about 15 minutes. Then, with only 3 minutes left in the 30-minute interview, the manager very abruptly spouted out that her manager was on the other line and she had to go. Her parting words were that she would email me. If you guessed there was no follow-up, you were dead on the money.

It felt so rude I was in shock. There was literally no time for me to even compose a response to that childish behavior.
