I had a series of 30min phone interviews. All interviewers were extremely professional, well prepared and switched on. Previous to Dell i had worked at a company where everything took at least an hour. Hence i was quite surprised to see how efficient one can be if all meetings and even interviews are done in 30mins. The interview method was pretty much following the behavioral interview style. In total I had four interviews of which one was face to face the others were over the phone.
