Worst Organisation ,having only of big buildings. My interview is taken of five hours . First when i entered in HR cabin ,then he was managing new building construction things with two other people, till one hour, then told me that fill the HR form and i will be back. Then he returned after half an hour . Then my technical interview person , came late of actual office time and i waited for half an hour again. Then my technical interview has been for 1 hour, thats ok. After finishing my technical interview , interviewer told me ,wait outside ,we will go to HR. then he went for lunch without informing anything, and i waited for 1 hour again. Then after i called to HR and he informed me my interview result . One of the worst management in a IT company .
