Presentation Technical Behavioral Case

We started with a 10-minute presentation where I had to explain how I solved a business problem using a technical solution, followed by a 35-minute technical interview. Then there was a 90-minute roleplay where two data scientists acted as stakeholders (one technical, one non-technical) and I had to scope out the problem. Finally, I had a 45-minute interview with the hiring manager.

Behavioral

I had a first interview that wasn't technical and it felt really constructive and genuine. The interviewer had a positive attitude. I didn't get the job in the end, but the interviewer was upfront about why I wasn't chosen (they needed someone more senior with stakeholder experience) and was happy for me to apply for other roles that might be a better fit.

Behavioral Technical Case Presentation

Had a screening interview with HR. Then an interview with the hiring manager where we discussed a past project. After that, a technical screening with two Data Scientists. They presented an ML use case simulating a client scoping session: prediction of gas consumption. They walked me through all the ML steps: Data understanding, Handling missing features, Model selection, KPIs. I was given time to ask questions and make sure I understood the use case before starting.
