I applied for seasonal position but didn't get accepted because I requested one weekend off for a school conference 2 months in advance.
My interview appointment was for 8:30am and I tried arriving early for it, but the Human Resource building doesn't open until 8:30am. There were about 20 people waiting outside of the building for interviews and various things. When the building opened, we had to go through security and fill out a quick form and wait in a waiting room until they called your name. When they called my name, I introduced myself and sat down. The interviewer asked why I wanted to work at Universal. He then looked at my form which asks if you need any time off, I had requested a weekend off for a school conference that I am presenting at, he asked me about it and then said that they were unable to accommodate this request. And then he sent me out, didn't even get to finish the interview, it lasted less than 5 minutes. So don't even bother applying if you need any time off.
