Pros
Really good experience to add to your resume. Big and diverse projects that will look great and give you some very practical experience. I would recommend this company to entry engineers for their first few years to get that resume padded and to learn practical skills. The company is big enough that if you ever hit a road block you can reach out to someone in the company to help.
Cons
Expect your salary to be lower than avg for your position. Yearly cost of living raise will barely keep up with inflation. Out of cycle raises take months to go through if they ever are even approved. Benefits get worse and worse every year, bottom of the barrel for the industry too. 3% 401k match, no HSA match, high premiums and deductibles. Rumor from upper management is that benefits for 2020 are being cut again! Engineer jobs are now starting to be outsourced to Eastern Europe and Southeast Asia because they are quote "ten times cheaper even if half of it is wrong". This is causing a lot of angst among the engineers in America. Literally everything is subcontracted out to save a buck. Every year for the past 5+ years a section of the company has been subbed out to save money. IT was contracted out to IBM but they constantly close tickets without actually fixing the problem just to meet their quota, no standard IT protocols across offices, different answers to easy questions depending on who you get a hold of in IT. Printers were subbed out but nobody came to actually set up the printers at your office, the new company just dropped them off and said good luck. We have to manually track each print since the tracking software was never set up correctly and IT won't deal with it since its a "printer company" issue. Facilities was subbed out and now nobody knows who to call to fix any office building issues, you get the run around depending on who you contact in upper management. Admin staff were completely gutted leaving all the overhead that Admin performed to now be done by the engineers. All the above now has to be handled by the already overworked engineers. Nothing can save this company it will eventually collapse from its own weight, turnover is insanely high, whole offices have vanished within the last year due to turnover.
