Hi,
I shaved, wore a tie dress shirt and khakis. I was the only one in the initial group interview who did so. I wanted to stand out and look neat and presentable.
The first "interview" was a group of people. HR reps described the job and took us on a tour of the facility. We were taken outside one at time and asked if we were interested and if so, a second interview was scheduled. That interview was a one on one with an HR person and the questions were pretty standard. What is your schedule and when are you available, why do you want to work for UPS, what would your former (or current) co-workers say about you etc, why would UPS want to hire you. After that interview, I think I got a call in a couple of days saying they wanted to move forward in hiring me and I had to give an authorization for a background check. Once all that was done, I think I got an email telling me to report on such and such day. Oh, training was a couple of hours of watching videos and taking quizzes. The first day of actual work, I was unloading trucks and have been doing so since then.
Be confident, sincere and polite.
I felt it was fairly easy to interview.
I am a package handler, was hired in October of 2011 and can honestly say I love my job. I don't make a lot of money of course, but I have lost about 30 pounds, I am a lot healthier, I am 47 years old so this is the best paid for exercise I have ever had. I like the group of guys I work with, and I like getting paid to exercise. I have worked in the corporate world for over 25 years and am currently a full time college student obtaining my degree, I have found this to be the best part time job while in school. I don't have to think while doing it and I can "study" in my head while working.
For the first two weeks, I and the other new hires met with a safety person for the first ten or so minutes of our shifts. At that time, the methods were re-iterated and any questions we had about the work we were doing were answered. I have followed the methods in lifting and moving and lowering and thankfully other than being sore have remained injury free. I say this because again, I am older. My joints are older and I was very out of shape, having never worked a physical job before. The first month or so I felt like I wanted to throw up for the first hour of each shift. I did not think I would be able to hack it. I always got help with any package over 70 pounds and was exhausted at the end of every shift. I can say my shop built us up slowly by graduating us to heavier lines at a reasonable pace. At this point, my strength has increased quite a bit, I have no problems lifting irregulars over a hundred pounds, I no longer feel like throwing up and I can get through a heavy shift very easily.
Good luck. I am glad I applied for and took this job. I like it.
