- 1st question is easy algorithm. - 2nd is for read file and manage the data before write out the file for output. Both questions you can choose any language that you familiar with, for me I chose JS (Node.js). - 3rd question is query and join database. I cannot complete this one but almost. - 4th-7th, are about algorithm knowledge, like what the name of the algorithm, which one is better.

Don't take a lot of time on each question. The multiple choice questions take less time. I stuck in the database question then I skipped to the other question and came back.
