I went to the nearest DashMart for the coding interview. I was interviewed by a middle-aged white man with a strong classmate vibe; there wasn't much interaction during the interview. SD asked us to design a review system. Previous posts have covered this in detail, so I won't repeat it here. Debugging: Round-robin, also repeatedly mentioned on the forum, see this post: https://www.1point3acres.com/bbs/thread-1141686-1-1.html There was also a round of hiring managers asking behavioral questions. The experience was quite good; there weren't any particularly tricky questions, just common ones I had prepared for. The coding was the 5-minute interval problem: Find All 5-Minute Intervals. I've pasted the code below. The following content requires a score higher than 180. You can already view it. Generate all timestamps at 5-minute intervals between a given start datetime and end datetime. The datetime format is "Day HH:MM AM/PM", such as "Mon 10:00 AM" or "Fri 12:00 PM". The result should be returned in ascending chronological order.

Note that the week is cyclic and the start time should not be included in the result, but the end time can be, and the initial generation... The time should be exactly 5 minutes after the start time. I've heard their company has a bad reputation, is it very tiring, and is gradually trending towards becoming a toxic business?
