The position is for a Modeling and Optimization Software Engineer.

There are two rounds of interviews. The first round is with the team leader, and the second round is with the department manager.

The first round's questions were simple, involving sorting. I just gave a few sorting algorithms, e.g., merge sort, quick sort, heap sort, etc.

The second round's questions were more relaxed and focused on behavior, like, "If a train stopped because of some issue, how would you know what the root cause is?"

No difficulties...
