CRIF Oracle PlSql Developer interview questions

After 2 hours of wait they took 1 st round which was held upto 30 mins and then after another 3 hours of wait they took 2nd round of interview which was also ended for 20 mins inspite of giving most of the answer correct ,I was not selected, I m not sure whether they have even vacancy or not bcoz they have not selected a single person at that day,they do not have value of your time.
