k6 interview questions — Hard
325 hard-level k6 questions from our Performance Testing bank, each with the correct answer and an explanation of why it is correct.
What this covers
k6 appears throughout Performance Testing interviews. At hard level, interviewers are typically checking depth under pressure — edge cases, failure modes, performance characteristics, and the trade-offs you accepted. Work through these, then explain your answer out loud; the second part is what interviews actually test.
