Conduent interview questions

Technical round , managerial round , hr round . Questioned security level for the web application. Then interface abstract static along with SQL server questions like primary key unique key union union all

I was called by the HR from the company itself in Jan 2019 but the HR process was just pathetic . Initially they said it's a scheduled walk-in drive but when I reached there , they had around 300 candidate for the role . I was called by the HR at 10:00 AM and I was on time and they provided some slip for interview queue and I had number 144. From 10:00 in morning , My name was called at 4 for the first time even they didn't think to ask candidates for lunch brakes and were fine to interview hungry candidates . When my name was called it seems that all the openings got filled already and they were just interviewing for the sake of formalities . Pathetic experience
