"@type": "Answer",
"text": "Zendesk interviews typically run 5–6 rounds: a recruiter screen (30 min), a technical phone screen (45–60 min), then 4–5 onsite or virtual rounds covering coding algorithms, system design, behavioral questions (STAR method), and for senior roles a leadership/culture-fit round. The full process takes 4–6 weeks from initial contact to offer."

"acceptedAnswer": {
"@type": "Answer",
"text": "Zendesk allows candidates to choose their preferred language. Most candidates use Python for its concise syntax, but Java, C++, and Go are equally accepted.

"acceptedAnswer": {
"@type": "Answer",
"text": "Most successful candidates spend 8–12 weeks preparing for a Zendesk interview. Allocate time as follows: 4–6 weeks for algorithm and data-structure fundamentals (LeetCode Medium), 2–3 weeks for system design practice, and 1–2 weeks for behavioral interview preparation using the STAR method. Daily sessions of 1–2 hours are more effective than occasional marathon sessions."
