I submitted my application for the campus job fair, completed a one-round on-campus interview, and took an online test. Subsequently, I was invited for an on-site interview.

The on-campus interview was half an hour long and focused on a single coding question: how to count the number of different words in a sentence.

The online test consisted of two questions. The first was to check for valid parentheses. Unfortunately, I don't remember the second question.

Regarding the on-site interview, I cannot reveal the questions as I signed a non-disclosure agreement. However, there was nothing unexpected, and I was able to approach it with ease.

The office environment was quite good, with large tables and great food.

Nothing unexpected, just very normal questions.

Like, how to count the number of different words in one sentence?
