Crayon Data Senior Software Engineer interview questions

Totally unamusing interview with indifferent panelists. I applied since they said looking for a person who is proficient in DS. But I was never asked a single problem related to DS. First round is totally basic questions. The interviewer looks like totally disinterested in taking interview and wasted both of our time. The second round went good but again the one question is totally messed up. Though I confirmed with the person about the problem, at the end its not the problem he actually said and do not completely know how to proceed further. Being both the interviews are taken by Senior Architects, at his point I severely doubt if this is the place I am looking for. The third round took by Engineering Lead, it went normal.
