Pros
PAC is a big company with a lot of departments, so I can only speak for my department, ALST. This position interfaces with many departments, from marketing to program and project management to tech pubs to engineering, in addition to meeting and working with the customer directly. Unique in the breadth of experience. This can be a good launchpad to jump into one of many other divisions at PAC. The managers are very respectful of personal time, vacation requests properly filed are rarely denied, and the culture is generally positive.
Cons
I don't think being an ALST focal is one of the better jobs at PAC. Skills specific to this department are not particularly transferable in the long run. Stress can be high at times given your broad responsibilities for planning, coordinating, and executing tasks with so many departments, often for several projects running in parallel. A number of colleagues in my short tenure have moved on to other departments and positions within a couple years. MTS I and II are hourly positions with OT, and previously the focals and managers had the discretion to spend extra time on priorities as they arose, but recently it's become tightly regulated at a much higher level. It feels odd to leave a priority task unfinished at the end of a busy day after a denied OT request, but of course it's best to be honest on your timesheet. However without OT, I'm not sure the pay is commensurate with the work. Upper management seems distant. Organizational and procedural changes at all levels, even from middle managers, are communicated only by e-mail.
