Avantages
As a fresher they will hire you just on the basis of your communication skills. They don't care if you have any technical knowledge or not. Apart from this in first three to four months they will pay you well during which all you have to do is just learn all the technical stuff, no work.
Inconvénients
Night shift is one of the main downside. So if you are a morning person don't even think about to join here as a "GIS ANALYST". During the training period of Gis analyst, they want you to learn every corner of Gis and that to in mere of 2-3 months. As an analyst you have to solve users problem but here sometimes people can't solve cases who's having an experience of 4-5 years then how you suppose from someone who don't have any technical knowledge and in a mere of 2-3 months training you think that he can solve users queries.
