Firstly, the other high-star ratings are a fabrication by SADA itself -- which practices deceptive public image techniques, like fake reviews on sites like this. As a former employee, I was present when such methods were being discussed.
The development team is grossly underpaid, as they focus most of their money on the sales team. While both are important, if you focus so completely on sales and short-change development, you end up with a company that successfully hawks sub-par products and services. But this is consistent with the used-car dealership theme exuded by the CTO -- Hovig -- father of the CEO, Tony. Hovig is a nightmare to work for -- not only because he's a pompous, disrespectful, micro-manager, but mostly because he's incompetent. He can't seem to get out of his own way -- unable to transition from the small business, used-car salesmen mentality that impedes real growth.
The other reviews on here that attempt to invalidate such critique by claiming they are written by disgruntled, incompetent employees are part and parcel of the previously mentioned fabricated reviews. I worked with some truly talented, hard working people at SADA who had been there for years -- but ended up leaving with the same grievances. There's only so much unhappiness a person can take in their professional lives. And as stated in other reviews -- there's a reason for the incredibly high turnover rate.
In a nutshell, SADA Systems is a small-time, small-minded company -- not due to the inadequacies of its employees, but rather the incompetency and egos of key players in management. As a salesman, SADA Systems might be worth the compensation, but as a developer, keep looking -- you deserve better. And as a technology company, that's a sad state of affairs.
