I applied online. The process took 4 days. I interviewed at HarperCollins (New York, NY) in Jul 2018
Interview
There was as brief phone call at which no questions were asked, followed by an in person interview with the hiring manager, which was followed directly by three more interviews with the current person in the position and the two supervisors. All of them were more structured as open conversations than questions and answers, and everyone except the hiring manager (who was quite rude) was very friendly.
I applied online. I interviewed at HarperCollins (Nashville, TN) in Jan 2014
Interview
There were several interviews, both over the phone and in person. A "behavioral" interview in front of a panel of several people that's pretty brutal. The whole process took months and I never heard back from them after the final interview. Got an email months later about a different job they wanted me to apply for.
I applied online. I interviewed at HarperCollins (Londres, Inglaterra)
Interview
Both interviewers were friendly and the interview felt fairly relaxed and laid back. However, I was never contacted with regards to the outcome of the interview, despite emailing them several times.
