Moonfrog Labs Senior Full Stack Developer interview questions

It was one of the best and quick interview experience . There was a small telephonic discussion .As I was aggressively looking for the opportunity , the interview was scheduled next day . The discussion was upon low level design , system design, DS and algorithm and two technical round (Project discussion ) . I got a call next day that I got selected and needs to come to office for rest of the joining work . One key thing I observed during interview is positive attitude ,good product and business roadmap which made my decision (join even the next day) easy .
