"@type": "Question",
"name": "What skills are most important for a Ar interview?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Ar interviews assess both depth and breadth. Core areas include data structures and algorithms (LeetCode medium difficulty), system design principles for the Ar domain, language-specific expertise, debugging skills, and cross-functional collaboration. Prepare concrete examples from past work that demonstrate technical impact."

{
"@type": "Question",
"name": "What system design topics appear in Ar interviews?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Ar system design rounds typically cover scalable API design, database schema design (SQL and NoSQL trade-offs), caching strategies, message queues, load balancing, and observability. Practice designing systems you would realistically build in the role — interviewers value practical domain knowledge alongside theoretical depth."

"@type": "Question",
"name": "How long does the Ar hiring process typically take?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Most Ar 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."

"@type": "Question",
"name": "What salary can I expect as a Ar at a top tech company?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Ar compensation at top-tier tech companies (FAANG+) ranges from $150,000–$350,000+ total compensation depending on level, location, and company. Base salary typically represents 50–60% of total comp; the remainder is RSUs and annual bonus. Use Levels.fyi to benchmark specific companies and levels before entering salary negotiation."
