The inmates were selected after they were interviewed by companies at Tihar's Jail No 3.
"All the 30 inmates with good character, who would be released in the next six months, were selected by 15 companies after they fulfilled certain criteria laid down by these companies," said Sunil Gupta, Tihar Jail spokesperson.
"A total of 30 companies were to visit Tihar Jail today (Tuesday), but only 15 companies arrived," Gupta said.
The inmates were offered jobs such as sales executives, data entry operators and marketing executives.
