I interviewed at Twilio. The first round was an online coding test.

I failed to clear the test, and I am writing this to help others understand what kind of questions were asked in the online test.

1. Given an array, e.g., [2, 5, 6, 3, 9, 5, 10, 56, 25], and a number X. Now, find all contiguous subarrays with length X. If X = 3, then all the subarrays are [2, 5, 6], [5, 6, 3], [6, 3, 9], etc.

Now, in all these subarrays, find the minimum element. And out of all those minimum elements, return the maximum one.

1. Given a URL, query the URL and fetch the JSON result (paginated). Find all subsequent results from new pages. Parse the JSON and do some manipulation on that data. Find a specific dataset from that JSON.
