I am 24 M and just completed my graduation. Looking for job.

Hello everyone. I've just completed my graduation in BBA General. I am clueless about what to do next and how to land a job and what skill set to acquire to land a high paying job. I don't know how to apply for a job properly and don't have any idea what am I worth for and how much salary to expect. I'm scared of interviews and aptitude questions they ask before the interview. Please help me and all suggestions are valuable to me and I humbly request everyone to explain everything and every step in detail if possible. I would really appreciate your efforts. Thanks in Advance.
