Rampant nepotism. If you are not part of the cool kids club (in other words white), you will not be selected to grow in your career. There is a lack of minorities in leadership as that is not the culture here as compared to any other tech company. SAP touts itself as an inclusive employer focused on diversity yet for SAP; diversity means gender equality (but you have to be white) – it’s like SAP jut woke up to gender equality and it was the latest buzzword out there. The other problem here is SAP is great at marketing itself - it is after all a sales and marketing machine and not a software company - so reality is very different from the illusion SAP markets itself as in terms of product or people diversity. If it was not for CoVID-19 a lot of people would have left sooner.
Lastly from a performance management perspective, it does not matter if you kill yourself to stand out for you probably will make 10% more than the lowest performer and forget about talking about career goals (re: see above for explanation).
