I was contacted by a recruiter, who called me for an in-person interview at the office. This was a 45 min whiteboard coding round, and they also used this time to sell some Qumulo kool aid and show off their downtown office. Based on this, they called me back again for a full day of interviews. I had 4 interviews on this day, and with the 5th interview to be with co-founder who was busy on account of some conference they had (quite understandable). They said I would have to come back on one more day to meet the co-founder, and were quite accommodating about the timing. But they let me know the next day that they were rejecting me. The interview questions were easy, 3 out of 4 interviewers were very pleasant and cheerful, and seemed to be solid developers as well, and willing to share openly about the company culture - except for the this one interviewer who was came across as dismissive and too proud of his own technical acumen. PS - Their whiteboard markers are non-functional, and fancy glass walls are not good writing surfaces making writing code in an interview there an irritating experience.
