Pros
Compensation seems decent at first, especially to those coming fresh from grad school. A good pool of young talent - that quickly begins to drain away since the best people flee as soon as they are able.
Cons
Tl;dr: run. Exponent is simply a meat grinder for fresh Ph.Ds. The internal incentive structures create and sustain a toxic work environment. Management is fully aware of this, and actively encourages extreme internal competition and exploitation. Survivorship bias is rampant at all levels of the company hierarchy. If you do decide to join up as a new graduate, be prepared for the following experience: There will be a honeymoon period lasting ~ 6 - 18 months, depending on your naivete. You'll find that there are many other new graduates with shiny degrees starting at around the same time. This won't fully register as a warning sign at first. You'll be excited and eager to contribute to any project. You'll ignore or laugh off the cynicism of more senior consultants. The exclusionary cliques and in-groups may trouble you a bit, reminding you of high school - but that's the way it is everywhere, right? Then, one by one, the people you started with will begin to leave. The best and the brightest will usually jump ship early. The first one will be easy to dismiss. The next one will surprise you - they were doing so well! The next two or three will follow quickly. By the fourth - if you stick around that long - you will begin to suspect that you are the sucker at the poker table. Eventually, someone will sit you down to explain how things actually work. All of your co-workers are your direct competition. The consultants one step up on the corporate ladder are also your direct competition. The manager your report to, the person who oversees and reviews your work - they are also your direct competition, and they do not have any incentive to help you succeed. Remember that scene from "The Dark Knight" movie where the Joker holds "tryouts" with the help of a broken pool cue? That's a vivid illustration of Exponent's approach to "career development." Insignificant things like diversity, collaboration, teaming, work-life balance and boundaries, positive work culture, development, mental health - all of that will be sacrificed for a sliver of UT. If you are not willing to make those sacrifices to enrich upper management - there's a crop of fresh-faced, hungry Ph.D. grads who will replace you in a blink. Tl;dr: run!
