I did the interview on karat. I met engineers from karat on a video call, they don't work for czi, they just do interviews for them. The interviewer was very nice and helpful often giving tips.

The interview process was incredible. I got to meet so many interesting and talented software engineers on different teams, as well as an incredibly caring team of recruiters. I remember the process involving a coding interview through Karat, a recruiter call, and then finally a coding and behavioral interview with two engineers at CZI.

1. karat (solved 3 problems) 2. Recruiter screen 3. 1st round technical, 2nd round 1 hour behavioral. The engineering manager looked disinterested and tired. The recruiter ghosted me for 2 weeks after the final and rejected me.
