Audio N/AQuick interview answer
Common failures around Tokenization and Context Windows: blocking the hot path, ignoring backpressure, and weak timeout/retry design. Assuming 1 token ≈ 1 word globally.
Detailed answer
Failure modes for Tokenization and Context Windows: Known pitfalls: Assuming 1 token ≈ 1 word globally. • Missing timeouts / unbounded retries • No backpressure when downstream slows • Assuming ordering/guarantees the runtime does not provide How seniors prevent them: Count tokens with the model tokenizer; truncate/summarize for limits. Parent context: Mitigate first, then root-cause. Check symptoms against: Assuming 1 token ≈ 1 word globally..
Full explanation
Name concrete failure modes and the mitigation for each — that scores higher than a vague “it can fail.” BPE/WordPiece/Unigram split text into tokens. Cost and context limits are in tokens not words. Multilingual and code tokenize differently.
