Pros
I was an previous employee of SAP who has since moved. Compared to other companies, SAP is well run, professional and courteous (something I have grown to respect the more I move through professional life). One caveat is it really depends on your line of business. I have good memories of SAP and I found majority of people in there to be very nice in general. I found SAP a nice place to work and never felt under undue pressure. One thing I found with SAP is its technology is everywhere so if you get good at ERP type technology it can open doors in lots of other companies. Benefits are ok, I found the stock plan was a great way to save and I generally maxed it out each month. Most of the management I found ok to deal with and in general nice. No big complaints or conflicts. Most managers SAP put in place are fairly competent and in general, sane. (This may sound like PR speak but that is my honest experience). I also found they are sincere about outreach things like including colleagues with autism, disabilities etc. Its a place that is respectful of differences. In general a chill place to work. However on the flipside it isnt overly PC or forcing certain things.
Cons
Certain lines of business of business have varying reputations. Some of them are overworked and over stressed which accounts for a lot of turnover. There is a obsession with SLA's often to the detriment of further learning or root cause (despite what management say). Compared to other tech companies SAP payscales are a bit anemic. If you are on a low grade it can take a long time to get up the payscale. SAP is also slow for pay rises and people will walk out the door who really should have been taken care of better. There is a lot of attrition in certain sectors because of this. I felt attitudes towards things like getting certifications or getting further education to be not the best. One manager point blank told a colleague he should have a think if he really needed a certain course. I found that a bit limiting. Pay is also slow to come and with the landsape the way it is, its easy to get payrises across industry. Galway location is in general a glorified support hub with some additional development work.
