Pros
Company provided vehicle takes about $50 per 2 week pay check. Siemens uses good project tracking software. You will be given as much responsibility and work as you can handle and then probably a little more. This is a crucible, no job after this will stress you out as much or challenge you to satisfy the customer under more challenging conditions. If you can handle the stress, you should have some impressive resume items. You have complete autonomy over how you run projects and your schedule.
Cons
PM position: Long 12-14 hour days where you will be expected to drive all over the bay area. The parts warehouse is understaffed so Project Managers and Techs will need to deliver parts unless you plan 3 days in advance. They only make one delivery a day regardless. Management at the end of every quarter will ask you to lower your project budget so that you can declare profit. When you explain that you will need the money for the project you are pressured into doing it anyway. Then, when you come in 15-20% under budget you are criticized for not making it 30% under budget (note all projects are bid to be be on budget). You will be given technicians who have insufficient experience to do the work because technicians are overworked and leave. Technicians will not be devoted to your project, they will be shared between other projects. Company Credit Card in in your name so if you don't file expense reports immediately, you will need to pay your bills yourself to make sure they are paid on time. People are overworked in general. Right before I started, someone died of a heart attach in the office. Another person in finance fainted while I was there and had to be taken to the hospital. If you look around, no one looks healthy or rested. There are always 3-5 emergency jobs that are going poorly and require all of the best technicians. This leads to new projects being understaffed to meet schedule and skills. Foreman/clients notice that and complain to which you have no real answer. You will be assigned night and weekend projects in addition to your normal projects. You will occasionally need to be at job walks at 6AM.
