The first round is a 5-hour (no kidding!) online assessment with 5 questions in total.

The first question is an open-ended, broad, and extremely generic question that basically demands you to write an essay (again, no kidding).

The other 4 are ambiguously described programming problems (LeetCode style). They clearly do not bother writing the problem descriptions in an unambiguous way, but they expect perfection on all answers.

In the answer for the open-ended question, I wrote about a little bit of everything, trying to give the reader a picture of what I had in mind. The feedback was a joke: "We wish you talked more about [xyz]."

Ask me specifically about [xyz], then!

I am glad I dodged a bullet.

Some questions involved some degree of parsing (either regular expression or else).

One was a proper LeetCode medium question.
