Entretien
All in all I would say nothing that someone wouldn't expect. Surprisingly, there was no coding part, partly expected.
Applied through a recruiter.
First round was a 1h phone call with a senior member of the wider analytics practice with, what it seemed from the phone, experience. General questions about machine learning, statistics, model evaluation, questions based on recent experience.
Second round was in person, a 2h session, 1h with a senior data scientist that was somewhat technical, again around ML. Second session with a Director (quite senior), more consulting question but still around analytics.
Last round with the Partner of the practice. Essentially, a 1h chat around life, a bit about Deloitte. I would say that if you are not a complete a*&hole, you are 95% on track!
Questions d'entretien [1]
Question 1
General questions about analytics, statistics, ML. For instance to discuss why would you choose a specific metric to asssess the performance of an ML model against the predictions, what is PCA in simple terms.
Regaring the consulting questions, it was more of a scenario test: Let's imagine we have a retail company trying to understand some business problem (can't remember), how would you go about asking for data etc.

Entretien
They have an interface where you see all of your applications and their status. Most applications are viewed by the hiring manager within a few days. First it was an HR interview, then a technical challenge, then interview with the hiring manager and the last step would be with the boss of the manager.
HR rep asked me if I would be ok with a lower salary than the one I get now, and when I said no they asked if money was my motivation which I honestly found quite impolite.
Hiring manager interview was ok, however I was shortly rejected from the position because I didn't have a technical skill which I never stated I had in my CV. They could have very easily read my CV more carefully and rejected me directly, instead of putting me in two rounds of interviews and making me spend time on the technical challenge.

Question 1
Questions on my motivation, expertise and why I am looking to change.
El proceso de entrevista para el puesto de Data Scientist en Deloitte fue profesional, aunque demasiado largo y con muchas fases. Hubo varias entrevistas técnicas y de recursos humanos, además de ejercicios prácticos. Aunque los entrevistadores fueron amables y el proceso estuvo bien organizado, considero que podría ser más ágil y eficiente.

Question 1
Me mostraron varios gráficos y dashboards con datos de negocio y me pidieron interpretar tendencias, detectar anomalías y explicar qué conclusiones tomaría a partir de los datos. También preguntaron cómo comunicaría esos resultados a clientes no técnicos.
First round is CV scan and intro interview. 2nd round is a technical interview (take home), which aims to solve a classification problem, and 3rd round is team culture fit
