The tech screen consisted of two coding questions on CoderPad. The second question was a follow-up to the first.

I coded the first question fairly quickly, and all tests passed on the first go. For the second question, I decided I would run the tests to see which edge cases failed and handle them accordingly.

By the end of the interview, the second question also passed all tests. The phone screen interview process clearly mentions that they are focusing on working code, not optimization.

I don't know why they decided not to call me for the onsite loop, even though the code worked. My best guess is they wanted code that passed all tests on the first go.
