IBM

• Very complex work, which turns out as a good learning experience about processes and job duties.
• Good starting salary.

• Very hard to get a salary raise.
• If the branch you'll work was created by outsourcing, it is very difficult for IBM to separate customer and company values, making it more customer than company related.
• Very orthodox company, meaning that suits and ties are almost mandatory if you want to be considered as a "real" professional.

Listen to the voice of the regular employee more often, instead of listening only to management about issues that concern the bottom of the hierarchy more. I'm not saying to always listen to the regular employee, but sometimes they have a better understanding of the situation than management does.
