Boston Consulting Group Data Analyst interview questions

After getting referral for dara analytics role, they call for 5 min telephonic interview. Ask about brief intro and from when are you available to join. since I am a fresher and 1.5 mother is left to complete the degree so they told me 1st complete the degree then we will talk. and didn't call again 🙃

I applied online, then HR called me after that I received a code signal test link based on probability and ml MCQ and python coding, with medium difficulty. Post that i had two rounds of interviews based on our profile, projects worked on, questions based on ml, python data manipulation questions and casestudy. I didn't get any call post that, but there are totally three rounds of interview
