There were two 60-minute interviews: an ML coding round and a research chat. The ML coding round asked me to implement speculative decoding. I needed to write one normal decoding function and one speculative decoding function. The speculative function had the following interface in the prompt: The test case required the speculative-decoding implementation to produce its output faster than the nor…
