Apple

# Apple Interview Experience | On Campus Role:** SDE Intern Rounds:** OA + Technical + HR ### OA Topic:** DSA OA was mainly DSA. Questions from array, string, hashmap and basic DP. One question was little tricky, first I tried brute force then optimized it. Time was also less so need to be fast. ### Tech Round 1 Topic:** DSA + OOP First interviewer asked introduction and then directly started coding. One array question was given. I explained brute force first and then optimized approach. Then tree question was asked, mostly traversal based. After coding, interviewer asked complexity and some edge cases. Also basic: OOP concepts Process vs thread Stack vs heap Deadlock Mostly interviewer was asking why you are doing this approach, so just knowing code was not enough. ### Tech Round 2 Topic:** Project + CS Fundamentals This round was more about my projects. Interviewer picked one project from resume and asked me to explain everything. Architecture, why I used that tech, database, problems faced, etc. Then follow-up questions were there like what if users increase, what is bottleneck, how you will scale it, what if server goes down. Some OS and DBMS questions also came. ### HR Topic:** HR + Behavioural Pretty normal round. Asked: Tell me about yourself Why Apple? Why this role? Difficult problem you faced Team conflict Strength/weakness Future plans ### Overall Overall interview was good but interviewers were going deep into every answer. DSA was not super hard but need to know optimization properly. Most important according to me is **DSA + OS + DBMS + OOP + projects**. And one thing, don't put fake or copied projects in resume because they can ask very deep questions from it. Good experience overall.
