## Apple Machine Learning Engineer Interview Questions

Interview questions that appear in Apples Machine Learning interview fall under the following categories:

• Coding interview questions
• Machine Learning interview questions
• Behavioral interview questions
• Letâs look at the topics to prepare and sample interview questions in each of these areas.

Coding is an extremely important skill for ML engineering roles. Below are the topics to prepare for the coding aspect of ML engineer interviews at Apple:

• Youâre given an array of integers. Write a code to determine if there are three integers in the array whose sum equals a given value.Â
• Write a program function to clone a given directed graph such that the cloned graph has the same edges and vertices.Â
• Youâre given two sorted Linked Lists. Write a code to merge the linked lists such that the returning linked list is also sorted.
• Youâre provided with the roots of two Binary Trees. Write a code to determine if the two Binary Trees are identical or not.Â
• Given the root node of a Binary Tree âB,â write a code to swap the right and left children for each node of the tree.Â
• Write a code to reverse the order of words in a given sentence.
• Youâre given an array of size N. Write a code to search for the second largest element in the array.Â
• Youâre given an array A of size N. Write a function to find the minimum index-based distance between two elements in the array.Â

• Behavioral interviews take place during the on-site interview. They are an important part of the decision-making process. Below are some behavioral interview questions asked at Appleâs ML engineer interview:

• Tell us about a time when you worked on a highly demanding project that stretched you
• Tell us about the most important ML project you worked on in the past
• What have been your biggest challenges as an ML engineer?
• How do you ensure to maintain your mental health?
• Tell us about a time when you disagreed with a superior.
• Tell us about a time when you had to adapt quickly and pick up new skills for a project.

### Phone Screen

There can be up to 2 phone screen rounds. It will be a 30-minute informal conversation with a recruiter, who will assess your interest in Apple and the role and how well you will fit in the team. The first call will be with an internal recruiter, but the second call might be with a team lead since all the openings at Apple are team-specific. You will be asked questions about your academic qualifications, professional achievements, and past projects.
