Cameron Compression Controls Engineer interview questions

It was a rather informal interview. Instead of me telling them skills and projects that I have completed, the 2 gentlemen told me what I would be doing in the position. I was shown wiring schemetics and plc logic of their products I would be working on. I was also shown a project schedule and told I was going to be going to training so I could edit the information needed in the scheduler software. I was told that a decision was going to be made very soon and that there were several positions in the controls engineering department available. After 3 weeks, with no feedback, I emailed the HR representativ and the controls engineer. I was told I interviewed very weel but the position was filled.
