Joining the Crime Bureau of Investigation, India is a very honourable and tough task to do. A lot of candidates wish to become a CBI investigator and the salary of a CBI officer is high but changes with the post. There are two ways to become a CBI officer.

The first method is not related to UPSC. Candidates that wish to be directly inducted as a part of CBI can write the Staff Selection Commission’s Combined Graduate Level examination and clear it and follow the procedure.

Luckily, if you are an IAS or IPS aspirant, you can become a CBI officer through the UPSC exam. In order for that to happen, you need to become an IPS officer and serve for your cadre and then allocate yourself into CBI probation or you can also apply for the Deputy SP in CBI, which is a group B post. Unfortunately, this option can happen only when there is a vacancy, it is not a yearly recruitment process.
