OnGraph Devops Engineer interview questions

It is a 3 round interview first two technical rounds and then managerial round but be strict because interviewer will try to make you feel comfortable and also their feedback system is poor as myself had to mail my hr to tell my feedback rest dont know if you will answer the 70-80% of the questions but still no guarentee that you will get a call for next round!! thats really a confusing state and i think personally this company is greedy they wants to hire experienced devops guyss on less package!!
