First-hand accounts from people who interviewed at Fenergo.
Software Engineer
It felt like it went pretty well, though I didn't move on to more rounds and they didn't communicate back clearly. The feedback wasn't very clear either. They asked theoretical questions about React and Python. Also, about 3-4 behavioral questions.
- Can you tell me about your background and past experiences?
- What technical skills do you possess?
- What areas or domains have you gained experience in?
Software Engineer
So after getting an email to schedule a meeting, I had a phone call where they asked me about my soft skills, the product, and why I wanted to join Fenergo. The HR person was really nice and asked about my current role and why I'm looking to move. Then came a coding challenge on Codesignal, which involved building a timer in React, debugging and fixing code in .Net Core, and some AWS multiple-choice questions. It wasn't super tough, but I couldn't finish it within the hour. The whole process felt really professional and organized. If you pass these first two parts, the next step is a meeting with the Engineering team, which is more of a management interview focusing on cultural fit.
- What makes you want to leave your current position?
- What is your motivation for seeking employment with Fenergo?
- Can you share your understanding of Fenergo's product and the company itself?
Software Engineer
I had 3 rounds with Fenergo and got rejected. First was a technical interview with a developer, then a mix of behavioral and technical interviews with managers, and finally behavioral interviews with the IT director and a manager from the Dublin office. Communication with the recruiter was strictly via email and Teams, and they seemed a bit overwhelmed. The role has been open for over two months, and they're really trying hard to find the 'right' person with their budget. I was contacted about this position twice. The company exclusively uses Windows laptops. During our chat about Apple Silicon, the interviewer expressed regret about their old Mac setup and the inability to upgrade. When asked about managing tech debt, both the technical staff and the director gave conflicting answers. It seems developers are treated as subordinates and expected to strictly follow procedures. Local development processes aren't well-defined, and the absence of a QA team is surprising given the company's size.
- Can you explain basic Python concepts like generators, iterators, and decorators?
- How would you handle permissions for AWS S3?
- Describe your approach to code testing and quality gates.
