Behavioral Questions:
Tell me about a time when...
- ... you went above and beyond for a customer.
- ... you saw an issue that your team could face and *proactively* took action to mitigate it.
- ... you had to meet a tight deadline.
- ... you realized you did not have the skills needed to do the job.
- ... solved a complex problem in a simple way.
Technical Questions
- Tell me about a project you worked on and explain it to me in detail (technical work such as ML project, simulation project, etc)
- Say you want to predict how many units of an item you want to stock in a grocery store each day for the next week. How would you go about doing that?
- A/B testing of green vs yellow color for the buy button. How would you design this experiment?
- What is random about a random forest?
- How would you assess a model's performance on a dataset with unbalanced target classes?
There are three rounds in total. The process begins with a coding round, followed by the main interview loop, where you will meet the team and discuss technical skills, experience, and fit.
First round is fun, second round, which is also the final round involved 5 sessions, with different focus. For some sessions, not be able to present my story completely, time was tight, and interviewers were rushing.
Thrilled to have accepted the offer — the process was tougher than I expected. The first round was primarily technical, where I tackled an A/B testing design question that required detailed metrics and sample size calculations. Later, I faced a SQL query challenge focused on tracking customer purchases over consecutive months. Funny enough, I had spent quite some time on PracHub digging into similar case studies, which really helped me approach these problems confidently. The final round included behavioral questions, and I felt well-prepared overall.
