I had a phone interview, and the first question was very specific to web technology, focusing on the difference between REST and SOAP, along with other very specific questions. Another question required me to write a parser for a language. These questions were conducted via Google Docs.

The first two questions were tough, but I was able to get through them. However, for the last question, I had no idea what the interviewer was asking.

I interviewed with two people. The second interviewer had trouble speaking but was very friendly. The first interviewer asked questions I could understand, but he was very cold and sounded quite arrogant.

Write a parser for some language the interviewer made up.
