I was contacted by a recruiter soon after I applied.

The recruiter sent me a link to a Hackerrank test.

The test contained a total of 17 questions, with 3 coding questions and 14 MCQs.

1. Reverse words in a string.

2. Find the first number in an array that is not repeated (or repeated, I do not remember exactly).

3. Sort a given list of date strings.

4. function logsth() { console.log(this); } new logsth(); What is the value of this?

5. const cowsound = 'moo'; function makesound() { console.log(cowsound); const cowsound = 'baa'; console.log(cowsound); } What will you see in the console?

6. Some questions about left join.

7. Some questions involving the difference between transpilation and polyfill.

8. A question about what certain specified situations represent the correct HTTP status. The options were 401, 403, 500, and something else.

9. Which of the data structures can erase from the beginning or end in O(1) time? Options are: vector, dequeue, stack, segment tree.

10. Some questions about CORS.

11. Something about JSONP.
