Read other reviews and you'll see a very us vs. them dynamic between the Russian workforce and the rest of the company. Communication between departments is poor and, generally, adversarial.
The CEO and senior managers stay hidden (they're not even listed on the website and you rarely see interviews in the press). No one knows who is on the board of directors. The top managers make all the decisions based on loyalty to the CEO and little else.
Most of the internal communication is done by a single 40-50 page newsletter that circulated as an emailed PDF, once per quarter.
In 2015, the company allegedly used Russian employees without security clearances on a Defense Dept. contract. (Source: Google "Netcracker" and "defense department" and you'll see the scandal.)
There's been no change in leadership at the top of the company in several years.
