It's been really frustrating not receiving any response from companies that I applied for, but this opportunity is through a employee referral. The position is for a new team in eBay.

So far, I just did a phone screening with maybe one of their team member. It was a great experience and a nice talking.

The interview started with a quick self introduction and then some questions about the resume. The coding questions came afterwards. I don't think it is a good idea to share the exact problem here, because it is not special and people should really prepare for the algorithm rather than a certain problem. But I can say it is using DFS in a 2D array, a lot you might already thought of some great problems.

The key points is the follow-ups. The first one is "what if the input 2D array is read-only" meaning you cannot modify it.

The second one is "how can you save space if you created extra space to tackle this problem".

The third is "what is the difference betwee HashMap and HashSet?"

And the fourth is "how do usually troubleshooting Java programs?"

I think thouse follow ups are much more important than the question, since questions are there and you practice them every day.

To whoever is in an interview, good luck!
