Since you did not get the email address from the recruiter, it does not hurt to call and say : " Just want to follow up with you on the status of the application. As you know I am new to the workplace, any feedback on my interview would be greatly appreciate. I value your opinion very much. By the way, I would also like to thank you for your time to interview me. Sorry that I did not get your email so I was not able to send a than you letter." Then see if they get back to you.
What position did you apply for?
