Letter Head

Hi,

For QC1 , I am showcasing 2 innovation cases. For 1 case I have 1 doubt.
I have worked in Company ABC where I was part of the development of a product of ABC company and the product is in the market and is implemented in CDE Company. But ABC is not product-led digital technology. My Recommender who is supporting my work in a letter left the company ABC and is working in XYZ which is not also a product-led digital company.

Question when the Supporting recommendation letter has to be drafted for QC1, it has to be which company Letterhead, Company ABC where work is performed or Company XYZ where my recommender is working.


Thanks
SD
