A candidate should participate an open day. You should prepare and bring your own resume to show it to recruiters. There were a bunch of groups waiting for their turns.
I applied in-person. The process took 3 days. I interviewed at Qatar Airways (Goa)
Interview
Three day long process.
Went for the initial without an invite on the first day.
Got invited for the next day
Checked for any visible marks, height and weight, person to person interview
Third day
Another person to person interview, orientation.
Almost 5 rounds of interview. See how you interact with customers and asks you random questions that's not related to work. Interview spots opens around the world, so if you want, you can see the destination that's near you and go for a interview.
