Simple behavioural questions they just want to see how you would handle certain situations in the company. They usually hire internally and award the package handler who is performing really well in the company

First, I needed to apply on the internal career site. Then there was a 40 - 45 minute face to face interview with the sort mgr and another senior mgr. They made a decision in short order. I received an offer for the position within 3 or 4 days. I then started the new position 10 days later with a substantial pay increase from what I was currently receiving as a regular part time package handler.
