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 preparing to give me an offer,

and hoped that I could interview with an even 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 asked me about the terms of the offer I had currently received and then went offline.

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

so were they just trying to trick me into revealing salary information?

It left me feeling quite bad.
