It was a pretty standard tech interview process using CoderPad and an hour-long call with an engineer on their data science team.

First was a generic first-round interview with pretty Java-specific questions with their recruiter, followed by the coding interview.

The coding interview, as I mentioned, is an hour-long coding interview and was based on filling in an interface provided by the interviewer. My interviewer was incredibly friendly and helpful, even when I would stumble initially.

Overall, I would say just keep talking as you walk through the problem so they can see your thought process in working out the problem.

What is the difference between a comparable and a comparator?
