After doing operation executive role for 2 month in warehouse operations for which job roles I can use this experience mostly in banking sector for entry level positions

First of all, let me address that a 2-month experience might have helped you in learning something new but is not given that much weightage by the recruiters. Since you have worked as an operations executive in the warehouse, you now must have an idea of retail management. This learning of yours will not go in vain and will be useful in your future career roles.

Since you are most interested in the banking sector jobs, I must tell you that this experience might not get you a decent job there but after getting a relevant degree, you can apply for entry-level roles in this field. Customer service representatives, back-office executives, and operations assistants are some of those entry-level bank jobs to which you can apply. These positions will be directly available to you in a private bank after your graduation/master’s but to have these at a government bank you will have to crack the banking exams.
