I applied online. The process took 1 week. I interviewed at Aily in Oct 2025
Interview
The first interview was an informal and relaxed conversation with the Head of Data Science. He provided details about the company’s product, potential growth opportunities, and salary ranges for different positions.
The second interview was a technical one with a Data Scientist and a Senior Data Engineer. The first part focused on behavioral questions related to my resume, rather than strictly technical topics.
The second part was divided into two exercises:
Reviewing a few simple Python functions: I had to explain what each function did and suggest possible improvements.
Analyzing a short Machine Learning script that contained several conceptual errors. I was asked to identify and explain what was wrong.
3 fases y una prueba técnica primero de 45 minutos y si la pasas de otros 45 minutos. Miran si es mejor para ti estar en el equipo de Data Science como tal o en IA agentica y LLMs
Interview questions [1]
Question 1
Enseñan código y tienes que resolverlo o decir que está mal
2 rounds of interviews and then no response , nothing even after reaching out. The questions were not that hard , mainly about Python concepts, projects you have worked on and some ml Algorithms and SQL. Still believe that ghosting is very humiliating and disrespectful.
