She applied a job for both company A and B, in the same filed, same salary and same position. In company A, she will work at day while in company B, she will work at night.

The person responsible for the human resources of company A had called her before the person responsible for the human resources of company B called.

Unfortunately, the company A is the customer of company B. That's what she didn't know before.

So when the boss of company B told her to go this morning to the meeting where there are people of both companies, she refused for the reason that she can't work at night, as the company B mentioned in an interview. After saying that, her B company 's boss told her to still go to the meeting.
