I applied through university. I interviewed at Apple
Interview
1 OA+ 3 Interview rounds, on campus at IIIT Hyderabad. The initial 2 rounds were technical, the last was HR. The OA was simple. The interview focussed more on my projects especially 'Smart India Hackathon' Project and a distributed systems' project.

Reason:

1. Algo - Shortest path like Dijkstra/Bellman Ford
2. Factors considered - Distance + Heuristic Traffic values (i said i would generate it based on intensity on each road from satellite images)
3. How would you handle the case when Gmap suggests another route in middle of travel?
1. Running my algorithm on updated factors(mentioned above) after every specific time interval would do this job.
5. What is normalization. Need of it and explain with example.

1. ques 1- given a sorted array(may contain duplicates) and a number 'num' return the frequency of num. (told them all possible approaches and lastly coded the most optimised way(binary search))
2. ques 2- detect a cycle in the given linked list. return boolean answer.(told them all possible approaches and lastly coded the most optimised way(slow and fast ptr approach))
3. follow up of ques 2 - return the entry point in the linked list given the linked list contains a cycle (told them all possible approaches and lastly coded the most optimised way)
4. explain any one of your projects
Around 2 months after I submitted my resume for Apple software engineer position, I got a call from the hiring manager. He asked me what was the good day for the interview. It took half day for meeting 5 people. It was long hour interview for me. Each interviewer spent ~ 30 minutes and asked ~ 4 questions. Each interviewer asked questions in the different areas.
The interview was easy, we talked about technical stuff in-depth: os, drivers. If they think you know something, they would ask you till they find where your knowledge ends. So be ready
