None

They notified me about a second interview a month after the first interview,

but by then I had already found a job and politely declined.

Later, the supervisor in the United States contacted me and said they were ready to give me an offer,

and hoped that I could interview with a higher-level supervisor in the United States.

We scheduled it for Saturday morning, but the higher-level supervisor in the United States had something come up and did not show up that day…

The original supervisor simply asked me about the compensation package of the offer I had received and then logged off.

Of course, they did not give me the promised offer afterward,

so were they just trying to obtain salary information?

It left me feeling quite bad.
