Preguntas de entrevista para el puesto de Systems Developer/Python Developer en Think Future Technologies

I got a call that i am shortlisted for interview. i went for interview, stay there for 30 minutes and then they proceed further and gave me some questions to write down on paper. i cleared that test and gave it back to them in hardly 15 minutes. Then they check or whatever they done, i almost wait 30 minutes again. Then hr came and told me that interviewer is busy, pathetic. I said ok, i'll come tomorrow again. she said no, i'll call you when to come. I said ok. She called me next day around 5:15 and told me that in 15 minutes i have to come for interview. I said okey mam i am a superman, i'll be there in 2 minutes and if i am late i'll call batman for help. Seriously i want to say exactly like that but i said mam how can is that be possible to come in 15 minutes, you should've to call approx 2 hours before. Then she said okey, i'll call you on monday. Then on monday i called her 5 times, she didn't pick. i mailed her 3 times. Till now i didn't receive any reply. Pathetic.
