Preguntas de entrevista para el cargo de Senior Java/J2EE Developer en Synechron

Interview process was simple, quick and 1 day process. I have cleared 2 rounds of f2f techno managerial round followed by HR. HR assured me that I have been shortlisted and will get offer letter by next week. I followed with HR more than a month and each time I got positive response saying its under process and will get offer letter anytime soon. After more than one month of pain I did not get the offer letter, instead of that I got an assignment which I need to be completed within just 2 days. They clearly know its next to impossible to complete that highly complex and lengthy application within deadline. However, I submitted the application in 2 days and as expected they finally rejected my offer. I really feel cheated now. Guys beware of this kind of company.
