I am preparing for an interview. In my previous role as a consultant for a services company, I was responsible for a number of projects where I could say something along the lines of:
I worked on site for client company X, and while there identified problem Y which they were previously unaware of. By addressing it they were able to save Z.
In some cases the amount Z was pretty substantial.
On the one hand, these are concrete examples of where I have added value. On the other hand, they arguably might show company X in a negative light in that they had allowed problem Y to occur. Z is really the measure of the financial impact that I had on the client.
In an interview, can I fill in the blanks X,Y and Z and stay ethical?
There are other similar questions on this board, but they relate to levels of technical detail. This is not about technical detail but fiscal impact.
