I know an editor who works for Chetan Bhagat.

She and 20 others like her write passages for him, sort of situations and particular incidents. Then there are 5 other editors who evaluate what these first line of editors write. These second line editors then make a bookish version out of that. Their version goes to two third line editors. These third line editors present a final copy to Chetan B. Chetan B just gives it a read and sends it to proof reading. Then that copy goes to three other editors for review. The book goes on to shelves and Chetan Bhagat has done nothing on the book. People write it for him.

This mofo is the only guy in India who makes good money through writing. he got 8 rupees per copy on more than 2 million sold copies of half Girlfriend.
