I arrived at the venue at the scheduled time of 9 AM. It took them over 1 hour and 30 minutes to process resumes and send all candidates to an open hall. After another hour or so, an HR representative arrived and took me to a conference hall. Some basic Java questions were asked, and I was done with that stage. At 12 PM, I was asked to wait for the next round. I waited, we waited, and all waited... None of us had any idea when they would conduct the next round. I had 3 more interviews scheduled for the same day. All were missed due to the significant delay in their process. At 2 PM, I was asked to go for lunch. Another hour passed. Then, I was called for the next round. The surprising part was that the client was ADP. They kept us waiting until the client representatives arrived. I had a high-level technical discussion with the ADP representative. I was sure that I covered over 85% of the questions. I was overwhelmed with joy.

However, the result came back negative. I couldn't believe the words, 'You can leave for the day.' Were they kidding me? If my technical standards were not up to the mark, why did that person interview me for over 1 hour and 15 minutes? I was disappointed beyond my control.

I went to HR and asked, "You should have informed me in the mail beforehand that the interview was for ADP. Their interviews feel like a game; they play with desperate candidates." I went home, recollected all the interview questions, and verified them online. I was correct in more than 85% of the questions. If they expect 100%, candidates would prefer Google, Facebook, or Microsoft, not ADP or Capgemini. Remember this.
