It all depends on how many vacancies are available in the Indian Space Research Organisation. Usually, the Indian Space Research Organisation exam is held every year in form of the ISRO Centralized Recruitment Board (ICRB). If there are more requirements for engineers, sometimes it may happen 2 to 3 times a year. There is a requirement for each center, so sometimes center-wise vacancy is also available. I hope this will help you.
