I applied through a recruiter. The process took 1 day. I interviewed at TIS (Noida) in Sept 2016
Interview
The interview comprised of three rounds:
Round 1: Screening - Probably they were looking for communication skills.
Round 2: Technical - Analysis of your basic understanding of digital marketing, pressure handling capacity etc.
Tip: Interviewer was very friendly and supportive, they will give you ample amount of time so, don't rush to answer. Take your time and answer.
Round 3: HR - Discussion on academic profile, salary, rotational shifts etc.
