I applied through LinkedIn.

They sent me a link to do HackerRank within a week.

The test contained 4 programming questions that you had to solve in only 75 minutes. I found it completely impossible to solve these questions in such a short time; I didn't have time to finish more than 2 questions.

I think the only thing they can judge is how fast and good you are at solving these types of tests, and not how good you will be at work.

As expected, two days after taking the test, I got an email saying that they were unable to proceed with my application.

Polygons: Identify whether four sides can form a square, a rectangle, or neither.

Sort hotels list: Given a set of hotels and its guest reviews, sort the hotels based on a list of words specified by a user.
