I had started at a small company as a younger engineer making decent pay. Then we were bought by oracle. We received 0 pay increases for anyone despite being profitable before we were bought out. Instead there was a systematic stripping of benefits. We used to have free lunches, snacks, regular company outings, parties, runs etc. Not the biggest deal right? but oracle attributes a dollar amount to it and that's all you ever are too.
I was promoted to Senior Eng. No pay increases. There were several people that left my team because priorities became mismanaged by Oracle. That means more work for the rest of us. Still no increase. Instead of hiring qualified local candidates we were immediately pushed to outsource. There are now significantly more India devs on my team than U.S. ones. I am also a person of color and I know that there are other people in my position being paid a lot more than I am.
Work wise, our product was doing very well before we were bought. We thought oracle would mean an influx of money leading to better management and coding practices. Instead we were pushed from day 1 to, instead of focusing on customer needs, use oracle products. Convert all of our applications to use the horribly thought-out OracleDB, instead of PostGres. The database is not user friendly at all and really requires you to be a professional oracle db admin to get off the ground. So now I have to learn this on top of my other work, still no qualified team members, still no pay increases. The products suffer, the customer suffers, the employees suffer.
The tools they give you are outdated, this is not the place to go if you want to be doing anything current.
Upper management has no idea what they are doing and are pushing nonsense products and offerings(aka huge push for using blockchains for no reason other than press). "autonomous" db that actually requires way more upkeep than people are being told. Push employees to use products that are totally useless like Oracle's version of youtube and facebook.
It has been ~3 years and I'm leaving and I am one of the last ones in my office to do so.
