I found a job in a new career (although related to my current) that interested me. It just so happened that I also had a friend who worked at the company of the new job. So, I applied and I told my friend who kindly gave me a reference. My friend sent the reference via email to the hiring manager and cc'd me on the email.
I interviewed and it did not go very well. I know some of my takeaways that I need to work on, but I'd like to ask the hiring manager since this is a different career path then my current one.
Would acceptable to email the hiring manager directly?
