Firstly, HR will contact you with the information to book the travel. The flight and hotel expenses have just gone through the company's bill. You can also book the car rental and have a look at San Francisco before the day of the interview. The reimbursement policy is pretty generous.

I interviewed with three teams. Most of the interviewers were team managers. The first team asked a lot about the projects on my resume, as well as some knowledge that might be used in their group. They also asked something about basic language usage. The second and third groups asked some algorithm questions; they were common questions that you can find on LeetCode.

Do you know something about Java GUI and Java multi-threading?
