Zenly Software Engineer interview questions

Interview with HR then one hour interview with two engineers to discuss about technical topics. Then after that there is a home work. I have stopped at this point because I have received an offer for another company I was applying at the same time. However the interview process at Zenly gave me the impression that it is not a place to 9-5 workers, the interviewers mentioned that people leaving at 11PM is not uncommon.
