The selection procedure had three rounds
Round One: Written Test
Written test was really easy based on aptitude, you had sectional cut offs for every section.
Round Two: Technical Interview
Technical interview was the least and the most basic technical ever experienced. I was from electrical branch so they asked me about communication, transmission and technologies. Varies from recruiter to recruiter.
Round Three: HR Interview
HR interview was nothing but the judgement whether you can speak well or not. If you can speak in fluent English. You'll be asked whether you can relocate, you'll work to complete targets, you gotta say yes to whatever they ask.
