These EMC interview questions have been created specifically to familiarize you with the types of questions you might encounter during your EMC interview. Good interviewers, in my experience, rarely have a specific question in mind for you to answer during the interview. Instead, questions usually begin with a basic idea of the topic and develop from there based on further discussion and your response. We’ll go over the top EMC interview questions and their in-depth responses. EMC scenario-based interview questions, EMC interview questions for newcomers, and EMC interview questions and answers for experienced candidates will all be covered.

Interviews for Top Jobs at Data Domain
Marketing Interview
I applied through an employee referral. I interviewed at Data Domain (Santa Clara, CA)
Interview
Fairly straight-forward when HR contacted to set-up for an in-person interview. Once I showed up, a personnel introduced herself but wasn’t clear what her role was, asked a few basic questions about my general work experience. After a brief conversation, she got up to go get the hiring manager. Fifteen minutes went by (and I was beginning to get worried that they had forgotten about me in the conference room). Finally a guy shows up and unexpectedly told me that there has been a mistake–the job was no longer available. In utter shock, I said “Oh, well that’s strange.” In which he obnoxiously replied “Not really–not in this day and age!” I thanked him and left. He provided no apologies, no display of fault or embarrassment.

ApplicationI applied through a recruiter. The process took 2 days. In June 2010, I had a job interview at Data Domain (Sunnyvale, California). The interview was conducted via phone and on site, and I was asked a variety of unrelated questions. Interviewers appeared to find it difficult to conduct interviews while away from their desks. It turns out that they are only looking to hire expensively overqualified individuals. Due to NDA can’t really mention the questions asked.
