Pros: It looks good on your resume.

Cons: Disclaimer: You might have a different experience based on your team inside IBM. I was surprised to know that IBM operates in such a messy way. My team has 3 software developers, all in different areas, which means that they work solely on different projects. This is the recipe for disaster. There's no back-up and, of course, there's no handover process in cases of emergency. Version control wasn't used until recently, and guess what? It was we, the developers, who pushed for it. Let alone that since there are no seniors and technical team leaders, every developer writes the code the way they feel like, without any defined conventions or practices, which of course makes this code unmaintainable. There are no testers, and only developers test their own code. Our team is not a software development team but rather a team that has some developers, and that's why the management hasn't bought the license for a decent IDE, and we're stuck using free text editors. It's clearly not the place you would want to work at to grow your career as a software developer. But aside from development issues and problems, IBM has the worst compensation among its peers. It didn't provide the appropriate raise after currency floating, which was provided by lots of peer companies. Also, the annual raise is a complete joke. There are other operational issues that involve the renewal of contracts and other stuff that there's no room to mention.

Pros: Free arm to explore all emerging technologies. Immense resources to upskill in your career. Inclusive culture.

Cons: Need to have more product-centric works. Need to improve on being ahead of the curve.

Pros: Good, diversified technologies and processes.

Cons: Bureaucracy, strict processes, and some outdated technology.
