Initial recruiter call, live code test and chat with a tech lead, interview on karat and a final round with the CTO (all done remotely).
Everyone was hugely responsive during the whole process, and it really felt like a way conversations which was massive for me.
Interview questions [1]
Question 1
Karat goes pretty wide with the questions. Iirc there were around 15 on various programming topics and then a final more CS style question around common ancestors.
