Have you ever had a job interview with both knowledge tests and physical tests?

I am having an interview with a local big oil company. I was told by the personnel department that, if I go on to the second level of interviews, it will include testing for basic job knowledge AND a physical test. I can only guess they are testing for what may be the physical requirements of an office job, such as picking up boxes and bending over a file cabinet. Has anyone ever had a similar test? What can I expect? Thanks
