The company I work for was acquired by Siemens PLM last year.
I was worried at first, but it proved to be much better than expected.
First of all it should be noted that Siemens PLM Software is a different company than Siemens AG, with a different culture, different internal rules and quite a different business. Most Siemens PLM employees come from other acquisitions and they (Siemens) tend to keep the people and integrate them as good as possible(in our case all employees were offered contracts and very few decided to leave the company after the merger).
For us there was a slight downgrade in terms of internal systems (eg. from G-Suite to Exchange and Outlook 2013 and other such changes, but at least we can use Win10 instead of Win7).
On the more negative side, the process for traveling is a impossibly complicated and there are several other procedures as well that are unnecessarily complex and take a long time to go through.
Overall for me it was a positive change so far and my advice to Mentor Graphic employees is not to worry too much, change is coming but it will be slow and not disruptive.
Siemens culture is aimed right at business integration. They won't buy an organization and pretend to run it.
They will oversee it and merge planning with the other divisions, but this is measured and well staged. Siemens AG is a very old, very smart people and metrics driven company. They are a very good example of how to do this stuff right.
I used to work at a company which was eventually acquired by Siemens PLM (there were some intermediate merges and acquisitions as well). We had a pretty neat CAE (Computer Aided Engineering) product called I-deas - you could build a part then watch heat transfer or mechanical deformation take place under various forces and conditions.
Also it was funny how we found out about the acquisition. We showed up one morning and one person in next cubicle yells out "hey check out CNN, looks like we've been acquired". I was just an intern so didn't affect me much but other developers were pretty shaken by that.
I think they (g-suite, MS suite) solve a bit different problems and I would agree that MS suite is more suitable for established enterprise with e.g. ability to book meeting times and places, lync integration with e.g. tandberg.
