More than 70 percent of GST accounting work revolves around return filing and reconciliation.

Step 3: Practice Reconciliation Scenarios

Employers expect you to handle real business data.
So practice:

  • Purchase register vs GSTR-2B reconciliation
  • ITC mismatch cases
  • Tally ledger vs GST portal mismatch
  • Sales turnover reconciliation

Many companies will give you a practical test during the interview.

Step 4: Learn E-Invoicing and E-Way Bill

E-invoice is now mandatory for businesses crossing certain turnover limits.
You must know:

Similarly, for e-way bills understand:

Interviewers may ask real situations, such as:

  • How will you treat ITC when invoice is missing?
  • What if supplier has not filed GSTR-1?
  • How do you calculate interest on late payment?
  • What steps you take for GST mismatch?

To answer well, understand the purpose behind each rule, not just the rule itself.
