Garbage, don't bother. Online coding. Easy/Medium algorithmic problems that you need to implement in 15 min each. The thing is, they don't care about your code or thinking process, as you would expect from a coding interview. Forget about all this "speak out loud", "time complexity", "code readability". I spent a good chunk of my time explaining the complexity of the proposed solution and trying to keep the interviewer engaged, but apparently, all they care about are test cases. Basically, the guy went completely silent for the whole time and at the end it was: "one of your 7 tests is failing, rejected, bye." Like wtf?) I can't stress enough, your code/words doesn't matter. Even if it's a typo or something that can be fixed with "i+1" or "arr.length-1". Pathetic.
