I applied online. I interviewed at Lumen (Bengaluru) in Jan 2020
Interview
It was quite smoth and the questions are not that much tough..they asked fundamental c++ concepts and data structures. But the employees are very cooperative during the interview process. C++ and basic c knowledge is good enough..but you should have proper in depth understanding in this

Interview
There were two technical rounds, consisting of average difficulty questions. They communicated that I have been selected, but its been a month; there is no communication on feedback or HR round. Very improfessional attitude.
