First-hand accounts from people who interviewed at E.ON.
Graduate Program
The interview process included a self-presentation focusing on personal strengths and motivations for joining E.ON. Candidates were also asked to prepare and present on current topics within the relevant department. Additionally, a conflict resolution discussion and its reflection were part of the assessment. The overall atmosphere was very pleasant, with a strong emphasis on company culture and values, which should be evident in the candidate's presentation.

Customer Service Representative
It was a very disorganised assessment centre. It involved a group exercise, a one-on-one interview, and a short task that we had to present back. I was there for 4 hours, and everything was done in one day, which was worrying. A lot of people from recruitment were there observing, which was intimidating. After the interview, I didn't hear anything back, not even a rejection email. I'm angry I wasted 4 hours with no reason given for failing, despite having extensive knowledge of the energy industry with years of experience. Eon didn't provide any reason for not selecting me. It's possible my experience was intimidating to the interviewers from the recruiting department. I sense bias and discrimination at Eon.

Auditor
I applied directly in early March after the job was posted. In early April, I had my first conversation with the Head of and an HR colleague. The interview was friendly, informative, and went smoothly. I was told I'd get feedback within two weeks. However, that feedback didn't come until over five weeks later, only after I followed up, along with an apology and an invitation for a second in-person interview. The organization of it all was really poor though: I only got a written confirmation of the appointment after asking again. Crucial info (like a map and parking) only arrived about an hour before the meeting. I was met by HR on-site, but the actual technical discussion was virtual because the person in charge was sick. This interview also went well overall, but I found the many HR/standard questions weren't very helpful. At the end of the interview on May 23rd, I was promised feedback early the next week. No call or email rejection has arrived since. Even after I followed up again a month later (June 26th), I got no response. Instead, I only found out at the end of July in the applicant portal that I was officially rejected on July 28th - with no reason or personal notification. For a publicly listed company like E.ON, I think this application process is extremely unprofessional and disrespectful. If a company externally communicates that 'the person is the focus,' this behavior doesn't fit at all. It's even worse that this isn't an isolated incident, as I've had a similar experience twice before. E.ON really needs to review the quality and reliability of its HR processes. This includes binding deadlines for feedback, systematic reminders for those responsible, and transparent, appreciative communication with applicants. This behavior casts a very bad light on the entire company and gives the impression of internal organizational and communication problems. Especially in HR, such a lack of transparency severely damages the employer brand.
- Can you describe, with practical examples, how you've handled complex and difficult situations previously?
- Could you explain, in a structured way, your process for tackling challenging situations, the actions you took, and the outcome you achieved?
Strategy Manager
After 5 previous rounds, I had the final onsite interview. On Friday afternoon (without warning), I was tasked with preparing a presentation by Monday, which I then had to deliver. The interview lasted 3 hours, and I was surprised with a 30-minute case study that I had to complete. The professionalism of the potential managers was shocking. During the interview, expressions like: - "I prefer to leave half the positions vacant before hiring someone I don't like (which is legitimate), so all my employees currently work for 2 people.... (not legitimate)" - "I have a problem with men in my team..." - "We are a company of old, white men and I am here to break these structures...." were used. I think for such positions, qualifications alone should matter. Unfortunately, it was a very toxic conversation. When saying goodbye, they initially refused to shake hands, and when I actively approached all interviewers, nobody even stood up. This is terribly bad business etiquette.
- From a strategic perspective, what do you consider the most important direction for the company in the coming years?
