Atachi Systems Software Engineer Trainee interview questions

I applied through referal. Went to their office at ECIL Hyderabad on a SATURDAY on 9.30 am. The doors were locked till 10.30. Waited it out. Then I had two rounds of interview. First technical face to face and then HR round. I got the offer, but pay is too low, It couldn't even make ends met. So refused it.
