The process took 1 day. I interviewed at Lohmann Animal Health US in May 2012
Interview
I submitted my resume and cover letter. A couple of weeks later, I got a call to schedule interview. Be prepared to answer a list of questions. If they like you, they'll give you a call for a second round of interviewing and a tour.
The people were polite and they seemed to love the work environment and co-workers. You're not allowed to own birds, since they make poultry vaccines.
