Intuit Data Science interview questions

3 main questions: 1. write an algorithm to generate the probability of obtaining a random number based on a prior discrete distribution. Was asked all the relevant probability theory questions where applicable. asked to solve with and without using numpy library functions. 2. pick any ML algo of my choice and explain it at depth - decision trees in my case - how I have deployed it in a project before - covered all the conceptual details. 3. write SQL queries to offer discounts to customers that may not retain a premium subscription service - how would you determine who will/will not be a recurring customer?

Recruiter said hm interview and someone else interviewed me and gave me tech interview. She was very rude and unfriendly in the process ( looks angry and very late response to my question). Once it is done, she asked who contacted you? Recruiter? You are not good in the tech….The interviewer said primary key can be null and told me not good at tech.. I told her that I was referred by someone and then she immediately changed her face and attitude….funny experience.
