This is definitely a case where you should believe the hype! A reading of even a handful of reviews on the company should be a requirement for anyone seeking employment at McMaster. I read most of them myself, although it was only after accepting the job. That was mistake #1!
I won't get into much about the management development program, as that's already been accurately covered in many previous reviews.
As for the overall environment, it's a shame that with so many book-smart people at the organization, there is no independent thought. As soon as it was apparent that I wasn't drinking the Kool-Aid, it became hell to work at McMaster. Bullying, intimidation, and unprofessional remarks (often in writing!) were all a part of my experience...and these all came from managers!
I completed four rounds of interviews, including a writing test, and thought that vetted my skills and background. On my first day, I was alarmed to discover that I was still being questioned and treated as if I was interviewing for the position. This continued for my entire tenure. On my first day I also asked why there were no name placards on desks; instead, we were given maps to find other employees in the building. I quickly discovered that the reason for this is people typically do not stay long enough for others to bother learning their names.
My purpose in writing this review is not to try to change anything at McMaster, as unfortunately the company is so rooted in its ways that I doubt it will ever change, but to spare others from the spirit-crushing, madness-inducing environment. One of the most satisfying things I have ever done in my life was to get out of there on my own terms.
Now run, don't walk away from this place!
