IBM reviews

Some of the downsides of working at IBM are the "nerd factor," the cultish-ness and arrogance of some employees, and the fact that the attempts to build community are sometimes overbearing. Most people who work at IBM are very nerdy and socially awkward, which can make them uncomfortable to be around and hard to communicate with. IBMers also fully believe that they are the best and their company is the best and that just because they are working at IBM they are somehow better than any other people in the technology field. Another downside is that sometimes IBM doesn't realize that employees have their own lives and friend and don't want to go to lunch, happy hour, and paintball with co-workers. There is sometimes pressure to attend optional activities outside of work hours.

The company is too big with many policies in place to make quick decisions difficult. Processes to get things done can be slow.
