The hardest part of interviewing for a company like Warner Bros. is getting your foot in the door. I submitted my resume through the website for perhaps hundreds of jobs but never received a call. I asked a prior boss to make a phone call for me which got me the call for an interview for a job I was not hired for but now I knew the HR rep by name and called her when I saw another opening for which I was qualified. That is the job I ended up getting.
