Trending @Accenture; Can I get LOR from my leads?

Accenture provides credence letter, I got it from them but it's pretty useless tbh. They just mention the university name and your basic details, like name role and how much time you have spent..they don't mention anything about how good you were or achievements. You can't directly get a signed lor from your manager since it won't have the company letterhead which is mandatory in LOR's. Hope this helps.
