The interview process was very unfriendly. Didnt feel welcome in the company. The interview involved a test + behavioral questions + two case studies one with junior and the second one with senior member of the company
First round was an online case interview followed by a 45 minute in-person case. Final round consisted of two back to back 45 minutes long case interviews. Interviews were standard.
I applied online. The process took 1 week. I interviewed at Boston Consulting Group
Interview
The first round interview is just data science case interview. You talk about what data needed, which models to use, how to measure the model performance. You have to make the interviewer engaging.
