My interview got scheduled from recruitment agency. Interview took 10 mins. I reached there at 10:30 in morning as scheduled. 1 girl came and took me to interview room. She asked me questions like 1 year experienced guy like inner join, difference between stored procedure and functions, difference between abstract class and interface.

She never discussed about my projects or what type of work i do, I gave answers very diligently because i thought that she will start from basic and will raise the level slowly and i can say that i never got stuck with any question as they are basic questions. After there 3-4 questions she said "You can leave for the day." I knew that i was not selected. I came out of the company, i was shocked. I called the recruitment agency again but they said they will discuss with panel and will come back and they never came back.

I found it very unprofessional of them, if you doesn't like my profile you should not call me for an interview. Like this they have wasted their and mine time. That's not what i was expecting from XL Healthcare.

Difference between abstract class and interface?
