Pros
Interesting C++ code development but big learning curve because code base is very large and complex.
Cons
UP has no business developing software. They do not how to manage a large code base they acquired from another company They are rookies and they cut people for no apparent reason. UP has laid off 500-700 staff people in 2017 and another 600-700 people in 2018. They are NUTS and I would of never came to Omaha if I knew their history. They promised me a 2-3 year assignment and let me go after a couple of months. It might of been age discrimination because they had voluntary and involuntary "buy outs" for their older worker at that time .Luckily things worked out for me since 2017 in a new work environment and I am very happy now for last 1 1/2 years.
