BASF Chemical Processor interview questions

Well i applied online and got a call back a couple weeks later. At that time they told me to come take a test. The test was a hour long. I thought they gave me the wrong test because it had alot of questions that pertained to a engineering. After the test i was told i got a B grade. They told me that i would definitely be back for the second interview. The very next day i got a call to let me know they wanted me to come in the following monday.
