Pros
Training is intense but that is to be expected. There is support for you in the form of mentors, colleagues and trainers who are happy to offer advice.
Cons
Toxic environment where new recruits are constantly watching their backs for fear of being sacked. People are told they are not the "right fit" just a few weeks into the job despite going through a rigorous interview process, and can be asked to leave with no notice. While the company seems to offer a great package in terms of salary and other benefits, there seems to be little or no concern for people who fall behind on targets. The feeling when you start work that you could be sacked at any point, even three weeks into your new role, is unnecessary and unethical. New recruits are also very quickly "Gartnerized", encouraged to have "intellectual curiosity" but only in the Gartner way. There is no room for independent thinking or deviating from best practices. Asking "why" things are done the way they are is met by a disdainful "because they are".
