Knowles Corporation Project Manager/Applications Engineer interview questions

I got a call on a Sunday afternoon from the Dir. HR. He wanted an face to face interview then next day. I interview with him and he mention that I would be speaking to 2 others. During the my interview he realized that I did not have the experience needed for the job. The experience was listed as "preferred" on the job posting. Then I spoke to the next individual. Some how the third person was missing. I was very surprise to see how disorganized this company is in their recruiting. I missed few hours of work and lost of time just driving back and forth for no reason.
