One take home work followed by a call discussing two brain teaser questions, and a video call to discuss pre given material. Then an in-office superday, one about a material given and one unseen material.

Phone interview with 2 big questions, interviewer would introduce himself/herself first then ask if you had a pen and paper to write with. The interview would then begin with the first question. Interviewer would provide small prompts but the interview is mostly one-sided.
