Hello Rakshit,

it is not sure that DRDO(Ceptam) held every year, basically it conducts  after 1 recruitment cycle is completed. so, next year exam based on the time taken to complete one recruitment cycle by the previous year.  but from the last 4 years they are conducting .

Ceptam 05 : 2012

Ceptam 06 : 2013

Ceptam 07: 2014

Ceptam 08: 2016

Ceptam 09: 2018 and 2019

here is the link for your reference:
