Krypson Infomatics interview questions

I have applied here for Magento Developer Profile and their HR aligned the Telephonic interview and for the interview time I waited for 10 mins then called HR that I am waiting for the interviewer but didn't recieved any call she said let me check and then I called her again after half an hour she then didn't pick the call. I then replied on the email that, please let me know if you will reschedule the interview or this position of Magento Developer is already filled. Till then I didn't receive any call or email reply nothing..... And I really left my current from current office specially for the interview and this is what I got in return. No single clarification, no reply, no call......
