The process started with a small phone conversation to gauge interest and high-level of skills. From there, a coding test was delivered, with a few different, interesting problems to try to solve.

Once that was done, there were two phone screenings, both standard 1-hour technical screens. The first had some basic technical questions, along with a verbal description of a problem and solution. The second involved some linear algebra (so please study up on it, it is actually relevant to the job) as well as another coding problem, this one more in depth.

The next step would have been an on-site interview but the process ended here for me.

Due to NDAs, I can't share anything specific, but remember to study your linear algebra for the phone interviews, and keep efficiency in mind for the take-home coding problems - use large data sets!
