Pros
I learned a lot of technical skills and processes in the beginning, and while I was learning to excel at existing processes (and did not attempt to improve anything) my experience was decent
Cons
Senior leadership was very insular and made a performance of being open to technical improvements, but was threatened by any reasonable & defensible suggestions made by low-medium level employees. Management was callous and seemed to resent or ignore any indication that technical improvements could be made. Management attempted to use (inaccurate and poorly researched) scare tactics to keep me from leaving my position when I asked about transferring internally. Management once called a very competent coworker of mine "insubordinate" and threatened termination (over a text message) after that coworker researched, presented, and tried to implement a new, more efficient process. I was once told by management that it was "Dell culture" to interrupt the presenter in meetings. An aggressive culture was encouraged, and questioning my coworker's intentions became the norm - in retrospect I believe I had several close coworkers who were actively undermining my initiatives and misrepresenting my work to higher-ups in order to secure their place in the hierarchy. I did not feel like my technical leadership had the "whole picture" in their head while planning our technical roadmaps. I feel that over the course of years I did more impactful and relevant work than my technical leadership but was paid 1/3 as much. Overall, Dell felt like it was only a good place to work if you had secured a cosy position in the senior leadership hierarchy and wanted to coast for several years but was not a good place to work otherwise.
