I am digital cadre and want to crack innovator.

Hey that depends on ur interests... but for someone to clear innovator they need to become a full stack dev or a devops or a cloud Engineer.

Well each 1 of them is easy/hard in it's own way, u should choose among the list of paths which feels more familiar. And also choosing any track out of ur unit skills require u to complete the track least 1½ month before the announcement of the wings. The reason i say 1½ month is usually u would only get only 10-12 days to complete the tech track. Good luck.
