Interview questions [1]
Question 1
How will you add two lists in Python?
Example given. What would be the result of inner join (SQL)?
How do you calculate Gini Index?
Write a short pseudo-code (over Webex) for given problem.
I took a technical test, a technical phone screen, and had a virtual onsite interview. The position I was being considered for was changed in the middle, which could have been communicated better, though I applied through a recruiter. The change resulted in extra interviews and a lengthier process.
Phone screen, tech phone screen with coderpad sql, on site w/ couple of people from different teams. Overall heavy emphasis on the stats, not much actual coding. Roles are not for engineers, may want to pay attention to it
Total three rounds interview, pretty typical. Talk about projects, previous working experience, asking machine learning questions, ab testing and case study. They much care about how you solve the problem.
