I applied online, and the process took two weeks. The interviewers were not willing to give any hints about the questions. I answered one question the wrong way, which wasted a lot of time.

At first, we talked about the projects I did before and my working experience. Then, they gave me two algorithm coding questions:

1. Given two strings S and T, find the shortest substring in S which contains all the characters in T.
2. Convert a Roman numeral to a decimal number.
