Pros
Working for Clark Associates has been an extremely rewarding experience--I was surprised to see some of the negative reviews on Glassdoor. As a programmer, my experience here been excellent. Simply put, if you're a hard worker, you will succeed here. You will be compensated (both in terms of salary and position) for the effort you put in and the knowledge that you attain. Clark Associates really values a strong work ethic. The work environment here is far better than any company I've ever worked for. We're provided with free lunches just about every week, the dress code is very relaxed, there's a gym on site, and the office building is brand new. The employees here are friendly and all seem to excel at what they do. Management is also very lenient as to when you come in and leave, as long as the hours are put in. There are even several employees that telecommute a few days a week. As a programmer, decisions and code that you write every day directly impact the company's success, which is very appealing to me. I would definitely recommend Clark Associates, especially to other programmers.
Cons
As some other reviews have said, there is some turnover. That said, I have never seen an employee that was "inexplicably" fired. As I said in the Pros section, if you display a strong work ethic and competent ability, you have nothing to worry about. In the past, I've worked at companies in which there was NO turnover. Although it felt nice to always feel job security, there was always at least one individual you'd have to carry because they'd never pull their weight. Working extra hours because management won't cut the weak links from your team is not very fun.
