IBPS

PO and officer scale 1 are same in the banks.
In the rural bank's advertisement, they don't hire as PO but they hire as Officer Scale 1.
Officer scale 1 is an assistant manager grade in the banks
They work in all the sections of the bank branch during their probation period and after completion of the probation, they are given one work in the branch.
An office assistant is a clerical post in regional rural banks, in other govt banks, the name of the post is clerk.
So, clerks and office assistants are the same.

For specialist officer in IBPS, it depends on the vacancy. If vacancy is there for HR then post-graduation is required in either social work or HR field. MSW and MSW in HR you are eligible for both.

In order to become a lecturer, you need to qualify Net or SET exam. NET exam has more competition than banking.

Hello,
I think you should prepare for all the exams. In government jobs exams or competitive exams, the syllabus is almost same. So, you can prepare at the same time for more than one exam.
If you want to work in Indian banks, then you can prepare for IBPS PO, SBI PO or RBI exams. You are from technical field, so you can also prepare for IBPS PO exam.

I hope it helps.

You can join any coaching institute to prepare for these exams. These are very good options for your career.

Hi,
Qualifying IBPS is a far better option than pursuing PGDBF. Since recruitment via IBPS exam is taken by almost all banks specifically government sector, but if I talk about job via the course, there are limitations from one bank to another and specifically in government sector as they don't give it much value.
