(following the previous one) You got only TWO baby bottle sample. You would like to know the max height you can drop it without breaking the bottle. Let set the unit as 1 foot. And the highest height you can reach is at N feet. So how would you find the (max) safe height? (This is the one I think is kind of brain-teaser one.)

As some other person posted here interviewers were pretending to be tough which was quite funny. They some how want to get to a point where you feel discomfortable. After I have met with Product owner, CMO and HR person, they decided to get me meet with CEO. I must say he is the most arrogant idiot I have come across. I have spent about 15 mins with me, which is the most wasted time in my life. He just want to behave like he is the perfect person on the planet. And he went on for those 15 mins trying to tell me that since I am relaxed I am not interested in working there. I mean, what sort of an idiot will generalize that people should be nervous if they are interested in the job? He asked me if my parents are alive and when I said yes, he said his father passed away couple of years ago or so and thats the reason he became mature and I am immature for the same reason. I mean common!!! Since I went from a different location to Norway I quitely left it, had it been in sweden I would have taken this up with the union as he was quite offending in the interview
