Colloquio
I got interviewed by two Argentinian girls from RRHH. The interview started 8 minutes late without any notice. They gave me a very brief introduction to what the company does. She explained me that there are 5 interviews (RRHH, tech interview, peer coding, CEO and team lead, offer in that order). Later they asked about my current job and got lots of questions about why I wanted to change from my current company at the time. Then I got my chance to ask about the company, I had questions related to the way of working and the company culture. She didn't reply about the way of working because IT way of working wasn't totally clear for her, she said I would be able to ask this later on. About the company culture, she said that they work with tight timelines and under pressure. Finally, I asked about a salary range but she replied that this is only given after the 5th interview. She said she was going to contact me if I passed on the next interview and that moment never came.

The interview process at dLocal was impressively dynamic and fast. It consisted of four clear stages:
1. HR Interview: Initial screening and culture fit.
2. Technical Interview: Deep dive into specific skills and problem-solving.
3. Team Interview: Great opportunity to meet potential colleagues and see the team chemistry.
4. VP Interview: High-level discussion regarding strategy and vision.
The entire team was very friendly and well-prepared. It was clear that the interviewers had reviewed my background beforehand, as they asked insightful and relevant questions. Highly professional experience overall.

The interview was only 2 steps: a Q&A tech assessment, and a product/behavioural assessment.
I got a very good impression overall of the people who interviewed me, but the outcome has been delivered without any feedback.
I believe that not giving feedback to a candidate is something that gives a negative impression of the company, because this leaves a scar in candidates' memories, and this burns the bridges with this candidates should dLocal being interested in hiring them later.
Very unprofessional behaviour.

Tech assessment was mostly about databases, basic and advanced concepts, performances tradeoffs, etc.
Product assessment: relationship AI, past experiences, and regular behavioural questions.

The first interview is a standard screening with HR. The recruiter was kind but many questions were responded with "it depends on the team, in next steps you can ask the technical team to provide more details".
After that, I had a technical interview with an "Architect". It was a 1 hour interview where the architect would ask you general questions about Golang, system designs, technologies you have used. Honestly the interview went great and I answered almost all questions correctly, but I received a rejection email (written with an LLM but anyway) telling me that they won't move forward because "I dont have professional experience with Kafka nor CQRS". Even if I don't have professional experience, I know about those technologies and I could respond fine to the questions..
Advice for the company: if you have a hard requirement about some technology, PUT IT IN THE JOB OFFER. Don't make candidates waste their time.
