I applied online. The process took 1 week. I interviewed at Boston Consulting Group in Feb 2024
Interview
1st round was a phone call with HR just talking about my experience. Literally 5 mins.
2nd round was codesignal assessment. It was proctored (video recording, mic on, entire screen shared). Can only google for syntax. The mcq/ probability questions they asked weren’t very difficult but if you’re out of practice then they seem impossible. 3 coding questions on numpy/ sklearn/ pandas. Not difficult but if even 1 test fails, you don’t get a single point.

Question 1
Question on combinatorics. What is the probability of getting an ace if you draw 5 cards?
I interviewed at Boston Consulting Group (Boston, MA)
Interview
Coding challenge, then soft skills which i did not get to. Coding challenge was online timed in a third party tool. Not very hard but needed more time and didnt move quick enough.
The process includes six stages: HR screening, CodeSignal online assessment, basic pandas and data science case interview, followed by three business case interviews focused on practical problem-solving and business impact.
