Hi Dhiraj,

Do you want to know about recruitments in PSUs through GATE 2019?

The most important thing that you need to understand here is that for recruitments through GATE 2019, you need a valid GATE score for companies like BSNL, ONGC, PowerGrid, IOCL etc. And by valid score I mean the cutoff scores as published or announced by the respective companies, therefore, there is no general cutoff, the results will be company specific and please note that these scores are only valid for a year and not more than that. 

Secondly, according to what company you are applying, your GATE scores can either be used only for shortlisting candidates for further screening processes, for example in NTPC or, as in the case of BSNL, it can be used for a direct recruitment. Therefore, the validity of your scores also varies from compay to company. 

Thirdly, apart from your GATE scores, companies can also publish other eligibility criterias like your CGPA during graduation, age limit etc. 

For your refrence and for you to understand the recruitment procedure better, please find below a direct link to Careers360's article on PSU recruitments that explains in detail the eligibility, the list of companies accepting GATE and links to their applications. Also, you will find here, links to a number of companies' application details. 

Therefore, please read the article very carefully.
