I applied online and got invited for online test which was pretty tough but somehow I cracked and got selected for telephonic interview which was a bit tough and now waiting for HR interview

I was contacted by HR through Naukri.com. The Interview Process are smooth. There were 3 round of Interview as Technical , Managerial and HR. In Technical Round Easy to Medium Questions were asked regarding project and Skills mentioned in Resume. I successfully cleared this round. After 1.5 Weeks my Managerial Round is scheduled. In Managerial Round get some Question regarding my project and Some Question regarding Economics and market related concept and formula as the interviewer was from Economics background. I can't able to answer that. Verdict Not get selected.
