it was two rounds, i have been interviewd both rounds, but in the final round hard to digest without any reasons (technicaly ),i have been rejected, i have done mudular components library dev for 2 years successfully, the interviewer was not ready to listen my answered he want in his way 2*2 - 4, evn i have mentioned 2*2 or 2+2 can be 4. . really disheartened however not down by my belief. Avil the interviewer has to learn the listening capacity and agree to all possible solution and best one for the team. please grow up !! guys think twise before apearing infront of this kind of selection.
