Hi, honestly that may vary depending on the hr or recruiter responsible for that position. I’ve always reached out or did follow up 1-2 weeks after I’ve applied for a job if I haven’t heard anything. Right now UPS may also be doing a lot of hiring for the holidays season, which for UPS, goes past New Year’s Day. So they may be loaded with applications. See if this may help with contact info https://ups.managehr.com/contactus.aspx
