According to police, Sukumari (25) consumed pesticide around 2 pm near a fountain at Vijay Chowk close to the Parliament House complex.
She was rushed to a nearby hospital where her condition is said to be out of danger, police said.
The woman consumed some pesticide as she was miffed over not getting a job in Central Coalfields Limited in Jharkhand after the death of her father who was employed with the company, said a police official.
According to the woman, her father died in 1989 and she was supposed to get a job on compassionate grounds.
She has claimed to have ran from pillar to post in attempts to get a job, but was not given one, he said.
The woman had arrived in the national capital yesterday and wanted to commit suicide near the Parliament House so that her plight would come into notice, police said.
