Maple Leaf Foods Engineering interview questions

I am writing this to tell you how disappointed, mistreated and frustrated I am over their hiring process. I have given Maple Leaf Foods over eight interviews, two of which lasted over three hours. Also, I made the trip from Hamilton to several different Maple Leaf Foods locations, which included Kitchener and numerous times to Mississauga. Furthermore, I was told I would hear back about the position within 48 hours, then I was told it would be within one to two weeks and then it was over three weeks. This company has wasted too much of my time because I have been giving interviews one after another to this company for over 3 months. If they were not interested in my qualifications they should have let me know after the first interview and not continue to waste my time. This is by far the most unprofessional company I have dealt with in terms of the hiring process.
