Working as an Associate Business Analyst, need advice on how proceed ahead with career

Hi Guys!!

So last year i joined a company as an Associate Business Analyst (in india), and I have been working here for the past 16 months.

This is my 1st job straight out of college as a fresher and I am grateful for the opportunity. But for the past few months I have been feeling inadequate with my work. Because although I joined as a BA but the project which I was allocated to, was mostly associated with providing support to the client. And for the past 1 year i have been supporting the client with the issues.

I have learnt a great deal regarding stakeholder management by interacting with client and leading the status call but I don't think I am learning anything of a sort that a BA does apart from client interaction.

So I will be leaving my job this October and I wanted to know how can I proceed ahead in my career as a BA. As company I give interview for will be expecting me to have written an FSD or BRD and I havent any done work like that, so pleae guide me how can I proceed with the interviews and learn what a BA actually does.
