NIIT Limited interview questions

I have applied online and after a couple of days, I received an email inviting me for the first interview. The next stages of the process would be two more interviews. They gave me the wrong address so I had to make many calls to finally know where the exact location was. The interview lasted 40 minutes and it took place at the entrance of another company next to the reception. Yes indeed next to the reception where so many people were passing by or talking.
