ADP Senior Web Applications Developer interview questions

I got the call from a consultancy regarding the Senior Web Developer opening at ADP Chennai on a Friday and the first round of Coding interview happened on the following Monday. When I reached the venue before 30 mins of the interview, I was asked to park the vehicle in the main road outside of the tech park. I was called in for the interview after 45 mins of the scheduled time along with 5 others. Each one of them were given a print out which consists of a specific problem to resolve and a desktop machine. The machine did not have access to internet. The problem that was given to me is to print the output in a specific format for the given input using plain Javascript. The question was pretty easy and solved the problem in 50 odd mins and informed the HR. After verifying the output, HR noted my details and said they will inform for the next round soon. But it has been more than three weeks and never got a call or mail for the net round. It looks like the HR team is scheduling the interviews for namesake. The interview process was happening to show interview counts to their organization. It costed 3-4 hours of my time and there wasnt any proper feedback from HR post interview. Note to ADP team: Please dont waste the time of candidates. They have turned up for the interview by taking permission or leave from the current working organization. If you want time pass or count, have interviews within yourself.
