"@type": "Answer",

"@type": "Question",
"name": "How long does the Infrastructure hiring process typically take?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Most Infrastructure hiring processes run 3–6 weeks: an initial recruiter screen (week 1), a technical phone screen (week 2), a take-home or additional screen (week 2–3), and an onsite or virtual loop of 4–5 rounds (week 3–5). Offer deliberation adds 3–7 days. Top-tier companies often move faster for strong candidates — express your timeline early to recruiters."
