I applied online. The online application includes work based scenarios questions. After which there's an online test which includes verbal reasoning, numerical reasoning and a diagrammatic test. I didn't manage to finish the verbal and numerical reasoning but the pass rate seems quite high. 2 weeks later out of the blue I was told I got progressed to the telephone interview page, a HR representative (the interviewer) called me to arrange a interview date. I was told the interview would take approximately 45 minutes and competency based interview. Given the questions that were asked, 45 minutes seems redundant as I completed in 20 - 25 minutes. The last question of the interview was a technical question/related to the field of the graduate programme. The one crucial thing I found after the telephone interview was all areas of competency E.ON is looking for are largely based on a PDF published for applicants Overall the process took 3 weeks.
