I have been notified that the interview will be on December, however, they changed the date to January. So I have much more time to prepare.

The interview involves many more design questions and only a few code questions. It is quite tiring to be interviewed from 9:00 am to nearly 6:00 pm with 5 people.

They all were very nice and smart. My feeling about the interview is very positive because one of my interviewers said, "I want you to do..." blabla after the interview. One of them also gave me a thumb-up.

However, I still haven't received the offer. I guess it is my fault for analyzing the complexity of a code. I was too tired and said "n squared," however, I meant 2 to the power of n.

4x4 puzzle with random alphabet and check all words in it.
