If you filled your name incorrectly in the IBPS application by entering your first name as your surname and vice versa, it could potentially lead to issues during the verification process. Here are some key points to consider:

1. Document Consistency: Your application details should match your official documents (like your 10th certificate and Aadhar card). Discrepancies might raise questions during document verification.

2. Correction Window: IBPS usually allows a correction window for application forms. If this is still open, you can log in to the application portal and make the necessary changes.

3. Contact IBPS: If the correction window has closed, contact IBPS customer support for guidance on how to proceed. They may provide specific instructions or allow for corrections under certain circumstances.

4. Keep Documentation Ready: If you need to explain the discrepancy, have your documents ready to show that the names are reversed.

It's essential to address this issue as soon as possible to avoid complications later in the recruitment process.
