How would you resolve a conflict between team members?
When I asked about what to optimized and also try to give a direction, he give me some hint with vague idea. Neverthless, he seems how to solve a high permutation / combination problem, where I try to through some of the ideas to reduce the dimension or go by store wise. The HM seems interests to solve this in real-time, when I asked about can a physical store be re-arrange in real time, got the response like solve in real time, change the physical store in a weeks time, not able to digest what we are solving, nor have any clue what we are trying to solve.
techncal questions such as how to deal with unbalanced datasets
Can you discuss a time when you showed leadership? Tell me about a project you were proud of.
What you be willing to write code?
When designing an experiment with many dimensions that could result in hundreds or thousands of unique cells, what do you do if you don't have sample size for all of the combinations?
Three focused behavior rounds and three focused tech rounds, which consist of a stats/ml session, a DS case study, and an software design round.
asked some machine learning and statistics questions. Like what is GBM? How does it work. Provide detail of the algorithm and how you assess it accuracy. The also asked on describing steps to building a model. Like what is your dependent variable, what is the definition, why you pick this definition.
Had an HR round and then a technical round where we talked about projects and then a case study. The issue is that the case study is a tough problem that they are dealing with; that is, something they have a whole team dedicated to and have been thinking about for months to years. Yet you are supposed to solve it in just a few minutes! So it really is not a fair assessment but that's how all tech interviews are today. One thing was the interviewer kept interrupting and didn't let me finish so I just figured he was trying to drive me toward to a set of exploratory questions on the case study. I did answer every question but got turned down.
