Cons
Long hours in software development ( in Creo Pro\E teams at least ), at least 10.5 hours of work\day. Very long time till promotion ( 5+ years ). No significant bonuses or none-salary compensation in lower or entry level positions. Future and long term development is not clear. You only focus on the short term goals. Experience gained will be limited to a very specific area. Staying a long time in the company will damage your future hireability. No quirks like free food as in other leading Software companies. Most of your time ( ~90% of total work time ) will be devoted to fixing bugs and supporting specific customers, R&D and new product devlopment is limited ( ~10% of total work time).
