When I previously provided support at Hong Chan (one of the predecessors of Data Systems Consulting Co., Ltd.), Hong Chan was quite good. However, hearing what it has become now is quite regrettable. Not long ago, I received an interview invitation from Data Systems Consulting Co., Ltd., but the invitation was not intended for me—it was for someone else. I was quite astonished that this company could be so bad that it even sent an interview invitation notification to the wrong person.
