Pros
Attractive company appearance and cool videos on the website. Some locations have nice offices. Job can be interesting and challenging besides the high pressure.
Cons
I have so much to say, but here is a quick summary: Exponent has serious internal communication problems and a troublesome business model. Micromanagement is observed everywhere. The company is so afraid of employee retaliation, yet they treated them badly during layoffs. Recent mass hirings then mass layoffs have proven the instability of the company. Its Business Development doesn't really "develop" businesses for the company. The consultants do- the scientists and the engineers have to engage businesses, bring in clients, and maintain business relations- all that besides what they already have to do in their professions. Recent mass layoffs have gotten rid of lots critical skills that the company and their clients will appreciate. Again, miscommunication is a serious issue. The management lacks of insightfulness.
