We’ve seen a very consistent signal in this process: Ifooddecisionsciences seems to care as much about how you think as what you know. The candidate described the interviews as patient, cordial, and surprisingly human, which matters because the technical bar still stayed real. What stood out was the mix of fundamentals, architecture, and design patterns — not as trivia, but as a way to see whether someone can explain tradeoffs clearly and build with intention.
A recurring theme is that they want engineers who can connect their past work to the problems in front of them. Multiple prompts centered on projects the candidate was proud of, their biggest professional challenge, and concrete experience with Kafka and event streams. That tells us they’re listening for practical systems thinking, not just textbook answers. If your background includes distributed data flow or event-driven design, this is the kind of experience they’ll want unpacked in detail.
We also noticed a strong emphasis on professionalism in the candidate experience itself: the process felt organized, the team invested in an in-person visit, and the interactions were respectful throughout. That combination usually means they’re evaluating for technical maturity plus collaboration style. The one cautionary note is that the post-process communication disappointed the candidate, so while the interviews themselves may feel smooth, candidates shouldn’t mistake a warm conversation for a guaranteed close.

Real interview reports from people who went through the Ifooddecisionsciences process.
What struck me most about the process was the balance between the technical part and the human side of the interviews. I was recruited through LinkedIn and the process took place in three stages, on different days: a conversation with HR, a technical depth round and, finally, an architecture interview. In my case, I also took part in #ElasSãoTech, so there was an initial registration stage and HackerRank before the rest of the process. After that, the company even paid for the trip to São Paulo to do the interviews in person, which made everything very organized and thoughtful.
The conversations were relaxed and the interviewers were patient and cordial. In the technical part, I felt they wanted to see everything from fundamentals to how I thought about architecture and design pattern best practices. Questions more tied to my experience also came up, such as talking about projects I am proud of and what my biggest professional challenge was. In another round, the focus was more on my experience with Kafka and event streaming, so it is worth arriving prepared to explain this kind of flow well. The overall atmosphere was very good, and I really felt comfortable showing what I knew. The only bad point was the post-process: they promised a response by a certain date and did not reply, which ended up being frustrating. In the end, I did not receive an offer.
Prep tip from this candidate
It is worth reviewing front-end fundamentals and also preparing to discuss architecture, design patterns and experience with Kafka/event streaming. Have ready examples of a project you are proud of and of an important professional challenge, because those questions came up quite directly.

Synthesized from candidate reports. Individual experiences may vary.
The candidate was contacted via LinkedIn and entered the process from there. In this case, there was also an initial application step through the #ElasSãoTech program before the rest of the interviews.
For candidates participating in #ElasSãoTech, the process included an early HackerRank assessment before the interview rounds. This appears to be a screening step to evaluate baseline technical skills.
The first interview stage was a conversation with HR. It was described as calm and human, and likely covered background, motivation, and questions about the candidate's experience and professional challenges.
The second stage focused on technical depth, from fundamentals to practical experience. Topics included design patterns, good engineering practices, projects the candidate was proud of, their biggest professional challenge, and Kafka/event streaming.
The final stage was an architecture interview, held in person in São Paulo. This round assessed system design thinking and how the candidate reasons about architecture decisions and trade-offs.
