I submitted my resume through an internal contact, and I was called within a week to arrange a time for an in person, one on one interview at the office in Frenchs Forest (so no phone interview screening). They emailed me all the details I required in advance - address, map, phone numbers, name of the interviewer, how to enter the office.
I arrived on the arranged day and time and was greeted by the interviewer. He had a generic question and answer sheet, but thankfully did not use it other than to jot down notes in the relevant sections - the first question I was able to read on the page was, 'Why do you want to work for Dell?'.
He was an experienced interviewer; and asked more general questions pertaining to my previous experience, knowledge of the role and the company, which gave me more freedom to answer questions without being stilted. Given that I am a recent graduate, he focused more on how my previous experience could relate to required competencies of the offered position, as opposed to the actual technical skills required. Having worked in the position being offered, he had comprehensive knowledge about the job and was able to answer and succinctly explain all the details I required.
A few days after the interview, he called to say they were not continuing with my application, having other candidates with more relevant experience as one reason, also saying that the manager who was offshore would most likely not be able to provide the hand holding I would have required (basically, I was under-qualified for this role). He provided feedback, which was also greatly appreciated.
In terms of culture, Dell in Australia is not considered a 'corporate' culture firm in which everyone wears a suit to work every day. I was overdressed in a black blazer, button down and a skirt - but it does help to make a 'professional' impression. Being a MNC, the interviewer did also say that the position would mean collaborating with people across the Asia-Pacific and Japan region, including India, Japan, Singapore and Malaysia - so time differences would affect how early or late you would start and finish.
