Oracle

Higher Management is kind and friendly.

Even though they take you as a Java professional, you won't be able to use it.

Late-night unnecessary work.

In Oracle, fixing an issue might take 5 minutes, but the process of getting approval and making that change will take almost a day. High, unnecessary process.

Hike and promotion are almost a joke; it is not based on rating. In a few teams, it is 80-20: only 80% of their team will get it, and the rest 20% will not. And again, it is not by rating; it is just picking randomly, mainly the 20% will be newly joined people (if no one joined after you in Oracle, you will be considered new for up to 2 years. I know it's a joke, but that is how it happens here).

Management will not understand or try to understand the true ability of an employee and just ignores their passion and abilities, making them do junk work.
