I applied to this company at our campus career fair, and within a few days, they scheduled me for an on-campus interview. One person interviewed me for about 45 minutes, asking only technical questions. They didn't inquire about my projects or anything else. I was asked to write code on a whiteboard and then answer questions about it. I was also told there would be three rounds of interviews.

Then, I received an email informing me that I had passed the first round and was invited to the second round – a telephone interview. It was a 30-minute interview with fairly simple questions and some extensions. Afterward, the interviewer began introducing the job and the company environment.

If I passed the previous round, an on-site interview would be scheduled approximately two weeks later.

Nothing difficult.

The first question is about the combination of HashMap and ArrayList. The best answer should be LinkedHashMap, but it's okay if you didn't know about this class.

The second interview question is to find the same element in two lists.
