The Interview was very straight forward, Total 3 rounds , 1 Techincal, 2nd Techinal & the final

Interview questions [1]
Question 1
What do you know about LTE , UMTS , SS7, TCP/IP , Unix / Linux, Telecom protocols
I was reached out to by an HR professional who was very nice to work with. They setup a call between us that progressed into speaking with the hiring manager. Once I spoke with them it was mutually determined that this wouldn't be a fit.
