I applied online. The process took 4 weeks. I interviewed at BT Group (New Delhi) in Apr 2019
Interview
Quite easy interview with only basic questions from your area of expertise. R1 was purely technical, one person joined over telecon. Was selected for R2 which happened on the same day where I was interviewed by 2 guys seemingly from the project team which was hiring. It went well, but no further communication from HR for about a month. I followed up and came to know the position went on hold. Hilarious! Extremely unprofessional.
