What do we assess during the interview?

In our data science interviews, we evaluate candidate knowledge in a wide ranges of topics including mathematics and statistics knowledge, coding (algorithm, data structure, and programming), machine learning, business insight, and communication skills.

These areas might be evaluated separately or as part of a business case analysis where we discuss a real business question and we ask the candidate to explain how they analyse the problem.

Case analysis questions usually start with a high level analysis and will be directed to more details to evaluate candidate's knowledge in the above areas.

A mock interview will help the candidate to evaluate their knowledge and skills in the main areas and find their strength and weaknesses. In addition, a mock interview is a close substitute for real interviews in a low stake environment.

This environment helps candidates to practice to manage their stress and reduce their mistakes in their real interviews.

What's the difference between 'Technical focus' and 'Stat focus'?

Stat focus is more for people with Math and Statistics background and questions are more focused on statistical models.

Both types are usually started with a business case and a general discussion on the approaching the question, then candidates are asked about ML or Statistical models that help answering the questions. Interviewers might ask some Stat and Math details to ensure the candidates have deep understanding of ML model. Finally, the interviewer might ask the candidate how they code based on a given data set.
