Can a person look for a fresh job at the age of 27?

Why not? Whatever field interests your friend, she can apply for those companies. Many companies take freshers as apprentice and pay stipend. Later they regularise.

you should come to india some time .. where unemployment is a serious serious issue .. people start working here at literally all ages .. nothing wrong at all

Yes, but they may have to take something entry level for a very low pay. Is she looking for a job that goes by her deree or something completely different? If she wants something different she should rrely on skills she may have. A temp agency is always a good place to start for employment, you get your choice of assignments and most will lead to permanant work. They do have temp agencies for almost every field of qork you can think of.
