Maverick10:
Expect some heavy grilling on Jeppesen approach chart, SID, STARS, airport charts and enroute charts. This is 100% sure that they will cover length and breadth of it.
Study ACE The Technical Pilot in and out. I bet you will not fail the interview. You may take around a month's time to finish the book. But trust me by the 30th day you will be very confident with every question that they could possibly ask.
For HR part, prepare a 45sec introduction and a few followup questions like "why do you want to join Jet airways?", "Who all are there in your family?" etc.
All the best.
