Real interview reports from people who went through the Ing-Diba process.
I went through three stages for the Software Engineer process, and the overall vibe was pretty friendly. The first thing that stood out was how much they emphasized soft skills and the code of conduct alongside the technical side. The interviewer was nice and actually helped me along when I got stuck, which made the conversation feel a lot less stressful than a typical screening. The technical questions were tied closely to the job description rather than being overly abstract, and one of the questions I remember was about what technology I had used during university.
The later rounds were more structured and HR-heavy. I had an interview with HR that focused on my skills, experience, and motivation, and it was conducted in both French and English. That part felt professional and relevant to the role, with questions like introducing myself and explaining how I work in a team. In the technical portion, the questions were fairly standard for a Java/fullstack profile: collections, OOP, beans, strings, and a coding question, plus a basic conceptual question about encapsulation and what it is used for. The only downside was that the interview felt a bit short, and the feedback from HR took longer than I expected. Overall, the process was pleasant and not adversarial, but you should be ready for a mix of behavioral, language-switching, and core Java fundamentals rather than deep algorithmic grilling.
Prep tip from this candidate
Be ready to explain your university tech stack, talk through teamwork and motivation in both French and English, and review core Java basics like collections, OOP, beans, strings, and encapsulation. Also prepare for a short coding question and don’t expect a very long technical deep dive.

Synthesized from candidate reports. Individual experiences may vary.
The process starts with an initial recruiter call to review your background, language skills listed on your CV, and overall fit for the Software Engineer role. Candidates should be prepared to discuss their experience clearly and may be evaluated on communication and motivation early on.
Next, candidates meet with the hiring manager and sometimes a future colleague. This round is businesslike and friendly, with emphasis on soft skills, teamwork, motivation, and whether your language abilities match what was listed on your resume.
Some candidates receive a practical take-home task tied to ING-Diba's domain, such as credit operations. The assignment is meant to assess how you approach real-world problems and make design decisions rather than to test advanced algorithms.
After the take-home, you walk through your solution with interviewers and answer core technical questions. Expect Java and OOP fundamentals such as collections, beans, strings, encapsulation, and basic coding questions, along with discussion of your implementation choices.
The later stage can include another conversation with the hiring manager and a manager from another team. This round is more structured and may be conducted in both French and English, with questions about your experience, motivation, and how you work in a team.
