"acceptedAnswer": {
"@type": "Answer",
"text": "Notion 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."

"@type": "Question",
"name": "What programming language should I use for Notion interviews?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Notion allows candidates to choose their preferred language. Most candidates use Python for its concise syntax, but Java, C++, and Go are equally accepted. Focus on clear, readable code rather than language tricks — interviewers evaluate your problem-solving approach, not language familiarity."

"@type": "Question",
"name": "How difficult are Notion coding interviews?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Notion coding interviews are considered medium-high difficulty. Expect medium-to-hard LeetCode-style problems with a focus on block-based editors, real-time collaboration, and document databases. Practice 100–200 problems on LeetCode with a focus on company-tagged problems before your interview loop."

"@type": "Question",
"name": "How long should I prepare for a Notion interview?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Most successful candidates spend 8–12 weeks preparing for a Notion 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."
