Good process in general, first HR, then with a partner and then with a technical manager. Last two were focused in biz and data science
The only thing I found bad was that they didn't call back from last interview, no feedback, no news about the position, so I just assumed I didn't pass
Smooth! They evaluate coding for data manipulation, and then some applied technical stuff related to DS. Towards the end, it's more business oriented. The interview process makes complete sense in relation to the job title.
I applied online. I interviewed at Boston Consulting Group
Interview
The interview consisted of a total of five rounds, and I'm currently at round 4. It started with a code signal online assessment (tested basic knowledge about data cleaning, data filtering, data joining with pandas as well as some simple ML with scikit). Then the first three rounds are technical case interviews. Each round consisted of about 10-15 mins for introductions, and 30-35 mins for a technical case interview, and then about 5 - 10 mins for questions.
Interview questions [1]
Question 1
If you could split your time working in three different aspects of your work (business related, coding related, data science related), what does the ideal split look like for you?
Online assessment
Round 1: technical case interviews + live coding
Round 2: Partner-led interviews + fit interviews + most in-depth technical case interviews
Overall semi-difficult but manageable.
Fun cases and nice interviewers
