Sent an email with cover letter and was invited to interview a few weeks later. Had to do a 5 minute presentation and answer few questions, one of which was a technical question

Asked to prepare a 5 minute presentation on: What I wish to gain from the placement? What attracts me to it? I was interviewed by a person from HR, a senior engineer and a graduate engineer. HR asked me general questions to see if i was the right for for the company and a technical question was asked by the senior engineer about something I had mentioned in my cover letter.
