This question already has an answer here:
One of the persons I want to give as reference contact for my applications has left the company where we worked together and the company has changed its name since then. Since I still worked there after the rebranding, I will give only the new name in my resume (the rebranding is shortly explained in the letter of reference I have from that company).
Normally I would list my contacts as "name, position, company, contact information", and I could handle one of the two conditions above with sufficient clarity – for example by writing "Company (now at Other Company)" for the former case or "Company (former Old Company Name)" for the latter. However, I feel I cannot give both bits of information precisely without creating a lot of "former's" and "now's" and nonetheless t would be not sufficiently clear who was where and when.
Any ideas how I could communicate this in a short fashion without having to write a half novel about it or, if not possible, which of the two facts is less critical to omit?
