Got referred in October, they reached out and we scheduled a phone interview a couple of weeks later. Question was easy, the interviewer did not really know Python syntax but never told me, so when I was writing out my solution I might've said something like 'ok so I only want this for loop to iterate through the rest of the list' and wrote something like array[i:], a few minutes after he wrote it he asked me what that was doing and took 5 minutes to understand it. First did a brute force of the problem and optimized it. All my complexity answers were right. Rejected the next day.
