Vantaggi
I see a lot of negative reviews from staff who works in the HQ of the company. I personally worked in the field (in Turkmenistan) for more than a year. I will be frank - although there were certain issues, this was still probably my best EU long term consultancy experience out of 4 experiences with 4 different companies in this field. Contrary to other consultancies which were saving so heavily that sometimes little, if anything was left for the actual implementation of the project, Human Dynamics' approach was more serious and more Client and needs-oriented. I dealt only with Project Director, never with Senior Management.
Svantaggi
Difficult to say. The project faced extreme restrictions when I worked there and started being implemented only when I lost my patience and left it, after spending more than a year in Turkmenistan. Since restrictions were so extreme, it's difficult to comment the cons. The cons can be commented when there are a lot of activities.
