Yatnam Technologies interview questions

I applied through online. For few days i didnt get any reply from hr. After constant msging through linkdin i finally got to schedule machine test. In machine test there were 2 questions . I used c programming language and i got output for both the answer , both releted with array and strings. And there was second round face to face interview i got some answers correct and some answers wrong. But as a fresher i cracked the machine test with full output and face to face interview was ok. I think i got the offer letter, when i call hr , the hr wont pick up the phn nor give any reply after 1 or 2 weeks i agained call the hr and told me to call eveng and then i called evng i got to know they moved to next candidate
