I have recently graduated in Mechatronics engineering, can i apply? I was thinking to apply as electronics and later tell them that i am in mechatronics since both fields are quite similar but i am afraid as they might blacklist me for lying.. any help?

one more thing, there is a note written on their website that candidate must be in possession of PEC Registration. Since i am a fresh graduate, i do not have the registration and it will take around a month at least so is there any relaxation or a temporary admission such that i can submit my registration later on?
