Extremely lengthy and involved interview process. Understandably as a pre-seed startup they need to be very selective of who they hire, but the process was slow and strenuous. Although the interviewers were nice and punctual, the interviews were quite unorthodox. There was no live coding. 1.5 hour hackerrank (fixing a React website, graph theory problem), then a 30 min conversation with CEO, then 1 hour online aptitude (IQ) test, then 1 hour architecture interview, then 1 hour logical riddles. Entire process lasted over a month and got a rejection after. I believe I wasn't given a fair chance to demonstrate my abilities that pertain to the job, but it seems like an IQ test score and logical riddle solving ability is what they're looking for.
