I received an email from an Apple recruiter regarding an opportunity with one of their engineering teams. I was very excited about this and quickly scheduled a phone interview.

My first phone interview lasted about 45 minutes and involved questions about my current work and experience, focusing on technologies I've used and some basic computer science concepts. If you have a grasp of fundamental CS, you can breeze through this.

Following that, I received another email about a second phone interview, which was about 30 minutes long. This session focused on my critical thinking and general problem-solving abilities. It wasn't too difficult either.

After this, the recruiter emailed to inform me they were interested in flying me over for an onsite interview.

I met with eight different people, in a mix of 1:1 and 2:1 interview formats, each lasting approximately 45 minutes, for a total of almost five hours.

I was asked questions about the Fibonacci series, linked lists (specifically deleting the nth node), and how to improve certain aspects of a system (though I cannot disclose further details). Overall, it was a pleasant interview experience, and even if I hadn't received an offer, the experience itself was rewarding.

Define a class for a linked list and write a method to delete the nth node.
