Perguntas de entrevista da empresa Mojio

HR call Interview with Director + giving a coding assignment 3 technical interviews(1 hr each ) The company needs to look into how they are putting down these questions as they were not prepared at all i was asked to code on a notepad which made me uncomfortable. The interview was easy but the guy asking the questions was mad about something and just didn't seem welcoming at all. Eventually after wasting almost around a days worth of work with them i was declined without a reason.

Three interviews with CEO, Data Scientist and Data Engineer. The interview was easy, I think the data scientist should prepare himself for the interview because his internet was super unstable and also he doesn't have much to ask. Data engineer asked easy SQL questions but some very technical data engineering questions that normal data scientists shouldn't know about it. Overall after three rounds of interviews, they were rejected without any feedback which is not appropriate
