In 2nd interview the guy asked me to implement multiplication without using * , looks like the guy was not prepared enough for taking the interview . When they scheduled it for the first time he did not call me , they rescheduled saying something came up and he could not call. I implemented it and said it os not applicable for -ve integer , looks like the guy was not sure if (-5*-7)=35 (he said that is not always the case) , I replied saying that I know if one is +ve another is -ve answer is -ve else answer is +ve .
