J'ai postulé en ligne. Le processus a pris 3 mois. J'ai passé un entretien chez Deloitte en avr. 2021
Entretien
Applied online and about 2 weeks later got a HireVue interview. They will ask some behavioural questions like why Deloitte, why consulting, describe your previous experience/education, greatest strengths/weaknesses.
The HireVue also has a coding portion where you have to solve 4 challenges that are similar to leet code easy. Other people have posted some of the questions under Data Analyst/Analytics interviews. Some questions were:
1. Calculate mod without using modulus
2. Get the Fibonacci number
3. Parse, join and output 2 CSV like strings
4. Given a string of moves, will you return to the starting point
About a month after the HireVue got invited for another round. This was a rapid fire statistics/machine learning theory round where they will ask any questions in the domain of math/statistics/machine learning and not necessarily related to your previous experience. They will start by asking easy-hard questions on a broad range of topics and gradually adjust the difficulty to match your knowledge.
Some questions: What are the assumptions of linear regression. How to evaluate linear regression? What are some problems with R^2? How to check for multicollinearity? Discrete time vs continuous time markov chains? Different types of distributions and what can they be used to model? How does PCA work and what are some problems? What are assumptions of time series models? How do you deal with auto correlation? What is the bias variance trade off?
Honestly thought I didn't get past that round but a couple days later they invited me for another round. This was more laid back and it was about past experiences and going through some case studies and thought experiments. They will also question decisions you made on past ML projects and ask slightly technical questions. It was more behavioral and to see how you problem solve.
2 weeks after that didn't hear back and I saw the job get reposted so assumed I didn't make the cut.

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.
Questions d'entretien [1]
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.
Questions d'entretien [1]
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
