* Work (ABAP) is mind numbingly boring! Majority of the work deals with the maintenance of legacy code written in a legacy language. You will spend 90% of your time in maintenance, fixing silly bugs in poorly written code handed over to you, rather than develop serious features.
* The proprietary development and testing tools used here are terrible compared to the open source alternatives available.
* Slow pace of work.
* Quality of people is not great (although there are exceptions); a lot of people know just enough for their day to day work. This can be rephrased as the lack of a strong engineering culture.
* Staying too long with ABAP can make you virtually skill less and unemployable as a developer outside the SAP domain. This is mainly due to the intellectual stagnation one undergoes working with ABAP.
All in all, this company is far from ideal if you are a passionate technologist, but if you like to settle into a low pressure job while drawing a reasonable salary and decent perks, this seems to be the perfect place.
