Recruiter applied on my behalf with my consent. I interviewed for KOC in Mumbai, India.
I arrived half hour before my appointment. I had to wait for an hour and a half approx. for my turn. Various job agent's representatives shall be at the venue. Don't worry, your agent will find you. Each agent will have brought their best candidates. They make you fill up a registration form, the bottom half of which will be filled up by the Interviewing panel.
Now coming to the interview experience, you will be interrupted frequently. Please remember you will only get 15-20 mins with the panel, no pleasantries will be exchanged, they will expect you to keep your answers short & to the point. Though be sure to greet the panel with a smile. Don't beat around the bush, if you don't know something just say so. They have about 20 -25 candidates to interview from morning 8:30 AM until evening 04:00 PM with a lunch break in between. If they don't like you, they may abruptly end the interview in the first 5 mins. Attitude does matter always have a smile on your face, don't appear nervous. They might appear intimidating but are quite nice outside the interview chamber. Dress well, I would highly recommend wear a light coloured shirt, a neatly pressed pair of pants, polished shoes & a tie. Facial hair is not recommended, but I got away with my soul patch. Documents will not be checked even though they ask you to carry everything.
They will ask you to wait outside after the interview is over. You will next hear from your agent regarding your result. If you made it, you'll score a one page offer letter on the spot. A detailed letter will follow after 15 days to a month. Post hiring until joining, you will have no direct interaction with the HR. You will only be talking to your staffing agency.
