Blip (Portugal) Interview Questions
& Process

The whole process was laid out pretty clearly. First, I had a call with a recruiter who asked about my background, my past work, and why I wanted this job. Then, I had a technical interview with the hiring manager and another team member. We talked about problem-solving, I gave examples from projects I'd done, and they asked some 'what if' questions about the job. Lastly, there was a brief chat about company culture, what it's like on the team, and what they expect. Everyone was nice and professional, and they kept me in the loop. It was a good, organized, and upfront experience.

So the interview process was this: first, I had a 30 minute screening call with the talent acquisition manager. Then, I had Technical interview 1, which was a session with product designers where they asked theoretical questions. Lastly, there was technical interview 2, where I had to present a case study.

After applying, there were technical challenges, followed by a chat with leadership and people. Overall, it was a medium-difficulty interview, asking very relevant questions about current challenges and my experience and vision regarding them.

The interview started with a quick phone screening where we had a general chat about the job, remote work options, and my skills. Then, there was a Devskill test that covered OOP, Multithreading, and Design Patterns, ending with a coding exercise. I had an hour but finished it in under 30 minutes. The next step was a technical interview with two senior developers. They asked about hashing, data structures, OOP, SOLID principles, multithreading, thread safety, and Kafka. For me, that was the end of the line because they felt I wasn't senior enough. Everyone was friendly, though one senior seemed disengaged. The interview felt a bit disorganized, and I struggled to understand the expected level of detail for answers. Sometimes they wanted deep dives, other times very basic explanations, like the obvious fact that using multiple thread-safe objects uses more memory than a single mutable one. This lack of clarity made it hard to answer questions effectively, even when I knew the material. I could answer most questions well, and the engaged senior gave positive feedback. Ultimately, the interview's vagueness hindered my performance.
