Status: BS Computer Engineering | BS Mathematics | pursuing M.Sc
YOE: 6 as SE
Position: AI/ML - Language Engineer at Apple
Location: Barcelona, Spain
Date: November 2023 - January 2024

Steps:

1. Introductory phone call
2. Interview A: Project Management and Scripting (60 minutes)
3. Interview B: Machine Learning and NLP (45 minutes)
4. Interview C: Tech Learning & Problem Solving (45 minutes)

B and C were series of questions to grasp my knowledge and experience on ML-NLP and how I would approach hipothetical scenarios/problems related to the role.

For A I have more information:
Questions (first 40 minutes):

• Explain what is a Hash Table/Map
  How would you implement it
  How to deal with collisions.
  How to deal with collisions without using extra space
• (based on my CV/previous experience with C#) What is the difference between dynamic and static libraries?
• Explain the difference between Depth First Search (DFS) and Breadth First Search (BFS).
• Explain what you understand as DevOps and your experience with it.
  GIT
• What is the difference between git rebase and git merge?
• How would you investigate a breaking change introduced between a high quantity of commits?
• What is your favorite git command? Why?

Coding challenge (15-20 minutes):

• (LC easy) Contains Duplicate
• (LC medium) One Edit Distance

Completed both coding challenges (second one barely on time). Went well on most of the topics/questions, but I believed I lacked professional experience relevant to the role compared to other candidates.

Reject: "moved on with other candidates"
