Questions & Answers about जब कर्मचारी खाता संख्या सत्यापित करे, तब पिन बदलिए।

Why does the sentence use जब ... तब ...?

This is a very common Hindi pairing meaning when ... then ....

• जब = when
• तब = then / at that time

So the structure is:

• जब employee verifies the account number,
• तब change the PIN.

In English, we often do not need then, but in Hindi जब ... तब ... is a natural matching pair.
Hindi can also sometimes omit तब, but keeping it makes the sentence feel clearer and more balanced.

Why is it करे and not करता है?

करे here is a subjunctive-style form of करना. In this sentence, it is not describing a simple present fact like does or is doing. Instead, it is used in a time-condition sense:

• जब कर्मचारी ... सत्यापित करे = when the employee verifies / should verify / does verify

This kind of form is common after words like जब, अगर, and in formal instructions.

Compare:

• कर्मचारी सत्यापित करता है = the employee verifies / is verifying
  (a plain statement)
• जब कर्मचारी सत्यापित करे = when the employee verifies
  (part of a condition or instruction)

So करे fits the instructional, conditional style better.

Why is there no ने after ?
