In order to get into bounty hunting, u need prepare:
+ Bitcointalk account: at least Jr.Member (for signature campaign), some bounty require it too, to prevent spam account.
+ Twitter/Facebook account: More followers/friends more stake/token you will get. Normally Twitter/Facebook campaign has a lot of participants now, so its less stake/token for each participant.
+ Telegram account: Some bounty ask you must to join their Telegram group. Therefore, Telegram account is must have.
+ Blog/Article/Video: You need writting skill for blog/article and media skill to create a video. This campaign will reward a lot of stake/token.
