I want to become a police officer

Hi Vignesh,
To become a class 1 police officer in India, you need to clear the IPS (Indian Police Services) exam which is held by Union public service commission (UPSC) every year.
1. The exam consist of two parts. A preliminary (prelims) exam is held as a first level. This prelims exam consist of two papers – general studies and an optional subject. It is a multiple choice question exam and is used just for selecting candidates for the next level of exam (main exam). The marks from prelims are not added while preparing the final result.
2. Once the candidate clear the prelims exam, they have to sit for the main exam. There is a list of subjects out of which two are compulsory and two are optional. Candidate can select any optional subject irrespective of the subject in which they hold a degree. This exam is very comprehensive and the candidate has to answer essay type questions.
3. Once the candidate have cleared the main exam, they are called for a personal interview round. It consist of around 45 mins interview with the board in which they try to see candidate fit for the post.
4. After the interview, marks from the main exam and interview are added and a final selection list is prepared which is called the merit list. Apart from clearing the UPSC exam, it is also possible to become a IPS officer after clearing the state PSC exam.
