Cognizant Software Developer interview questions

Worst experience in my life. Applied through their career website. They have scheduled the interview and I have gone through 2 technical, 1 HR round. The entire process took a day by making us wait and without asking us to go for lunch or anything for the whole day. After clearing the 2 technical rounds the HR asked all my past experiences and nothing else. Later she informed that I will get call for next HR discussion and will let you know the formalities. Its more than a month still I didn't get any update on my candidature. After sending a lot of follow ups they don't give a damn to reply. Careless ruthless, laziest and full of attitude people. Your very existence of your HR job is because of technical fellows. If they are not there you don't even have your jobs. Show some respect to technical guys. They are not your road side daily labors.
