My experience with this company was extremely disappointing. They do not stand by their consultants or provide any real support when problems arise with client organizations. I was left completely on my own in a difficult situation, and their communication was minimal and unhelpful.
Vector Synergy keeps a very large percentage of your salary while offering almost nothing in return. They present a professional image online, but behind that façade there is a lack of transparency, fairness, and respect for the people who actually do the work.
There are many other consulting firms that treat their consultants with professionalism and integrity. I strongly advise professionals in the international sector to avoid working with Vector Synergy.
