I applied online. I interviewed at LumenData (Bengaluru) in Feb 2026
Interview
2 technical rounds (Virtual) and 1 hr round (At office). 2 technical rounds completed successfully. Went for a HR round after that there is no response from them even after multiple follow-ups. Just waste of money for travelling and accommodation.
They just want to take interviews and waster out time, without providing offer.
