The interview process went pretty smooth. First phone round then I was called onsite. Did well there. HR sent me a email that they liked my performance in the interview and will like to go ahead with the formalities. But after that, they never contacted me. I emailed them after a week asking for my offer letter, the HR said the position is given to someone else and they won't be going ahead with my application. I think that was rude on her part for first saying they will go ahead and later rejecting me for the position. I rejected one of other jobs that I got because of Mathworks and now I won;t even get that one. This was the most unprofessional behavious I have ever seen by a big and reputed organization like Mathwotks.
